The Mariners retired Randy Johnson's uniform number 51 on May 2. The team retired the number in 2025 for Ichiro Suzuki.[1][2] The Mariners are wearing a uniform patch commemorating their 50th season.[3] The Mariners unveiled a statue for Suzuki in April and are planning to unveil a statue commemorating the 2001 Mariners in September. In August, the team celebrated its 50 seasons with a pre-game ceremony recognizing the top 50 players in franchise history and announcing that broadcaster Rick Rizzs would be inducted into the team's hall of fame. Left fielder Randy Arozarena represented the Mariners in the MLB All-Star Game.
On August 18, the Mariners suffered their worst loss in franchise history, losing 22–0 to the Milwaukee Brewers. They also failed to improve on their 90–72 record from their previous season.
On September 12, the Mariners beat the Athletics 19–1, their best margin of victory in franchise history.
On September 15, the Mariners lost their 82nd game to clinch their first losing season since 2020 and first in a full season since 2019.
On September 24, the Mariners were officially eliminated from playoff contention. Of all teams in the expansion era, the Mariners became the second team in MLB history to play 50 seasons and fail to reach the World Series. With expectations of competing for the franchise's first championship, the season was largely considered a disappointment by the fans and media.[4][5] At the conclusion of the season, manager Dan Wilson mutually parted ways with the team.
Offseason
Coming off an AL West division title and AL Championship Series appearance, the Mariners acted early in the offseason, re-signing first baseman Josh Naylor, who had been a 2025 mid-season pickup, to a five-year contract in mid-November.[6]
On December 5, the Mariners announced their coaching staff for 2026. Two former coaches left for bench coach jobs, with third base coach Kristopher Negrón joining the Pittsburgh Pirates and bullpen coach Tony Arnerich going to the Cleveland Guardians. Carlos Cardoza, previously the Frisco RoughRiders manager, was named the third base coach, and former Mariner catcher Austin Nola began his coaching career as the bullpen coach. Jake McKinley, formerly the Nevada Wolf Pack coach, was named the field coordinator, replacing Louis Boyd, who took another role with the Mariners. Seattle retained all other coaches from 2025.[7][8]
The Mariners made two trades to fill areas of need and sent out prospects, acquiring reliever José A. Ferrer from the Washington Nationals for catcher Harry Ford[9] and getting utility player Brendan Donovan from the St. Louis Cardinals for four minor leaguers and a draft pick.[10] The Donovan deal was done in part due to two former Mariners and FanGraphs bloggers, with Dave Cameron, Seattle's senior director of player personnel, reaching out to Jeff Sullivan, a senior analyst with the Tampa Bay Rays, to include the Rays in a three-way trade.[11]
The Mariners made smaller signings to fill lesser roles, adding Rob Refsnyder as a right-handed bat to face lefties[12] and signing Andrew Knizner and Mitch Garver for the backup catcher job.[13][14]
Pitcher Logan Evans had Tommy John surgery in January 2026, with an expected 12-month recovery.[15]
In January, the team announced that they would wear Seattle Steelheads-inspired uniforms on Sunday home games, replacing their cream alternates.[16]
Longtime broadcaster Rick Rizzs announced in January that he would retire after the season.[17] Fellow broadcaster Angie Mentink suffered a stroke in February.[18] The franchise also changed television broadcast arrangements, shuttering Root Sports Northwest after the 2025 season and moving production to MLB Local Media.[19] The team is broadcasting some Friday games on KING-TV other Pacific Northwest over-the-air television stations[20] and added former player Ryon Healy as a color commentator.[21] The team also announced in February that they would unveil a statue in September depicting Mike Cameron and Mark McLemore honoring the 2001 Mariners team that won 116 games as well as the 25th anniversary of the September 11 attacks.[22]

Spring training
Pitchers and catchers reported to the Mariners' spring training facility, the Peoria Sports Complex, between February 9 and 11, with the first spring training game held on February 20, against the San Diego Padres, who also train in Peoria, Arizona.[35]
The Mariners non-roster invitees to spring training included top prospects, such as Colt Emerson, Ryan Sloan, and Kade Anderson; former major leaguers on minor league contracts Dane Dunning, Patrick Wisdom, and Michael Rucker; and returning organizational players including Casey Lawrence, Austin Kitchen, and Guillo Zuñiga.[36]
Pitcher Bryce Miller and shortstop J. P. Crawford dealt with injuries in late February.[37][38] Both players began the season on the injured list, along with utility player Miles Mastrobuoni.[39] Mitch Garver won the competition for the backup catcher job in spring training, with Andrew Knizner electing free agency.[40]
World Baseball Classic
The Mariners had 16 players selected to play in the 2026 World Baseball Classic (WBC), held during spring training, including six minor leaguers. Outfielders Julio Rodríguez and Randy Arozarena returned to the Dominican Republic and Mexico, respectively, with All-Star closer Andrés Muñoz also playing for Mexico. Prior to the WBC rosters being announced in February,[41] both Cal Raleigh and Gabe Speier committed to the United States.[42] Josh Naylor was the captain for Canada, after previously playing in the 2017 WBC.[43] Reliever Eduard Bazardo joined Venezuela. Part-time players Dominic Canzone and Miles Mastrobuoni joined Italy. South Korea selected minor league signee Dane Dunning, while prospect Michael Arroyo and reliever Guillo Zuñiga joined Colombia. Four other minor league pitchers were chosen by other national teams.[41] Mastrobuoni suffered a calf injury during pool play and returned to Mariners spring training.[44]
During a U.S.–Mexico game on March 10, Arozarena, ahead of his first plate appearance, attempted to shake Raleigh's hand, which Raleigh declined.[45] Naylor made a similar attempt when Canada faced the U.S., though Naylor said after the game that he was joking with Raleigh.[46] Raleigh, who was hitless in the WBC, was benched in the final two games, including facing Rodríguez and the Dominican Republic.[47]

Season summary
March/April
The Mariners lost on Opening Day and split their opening four-game series at home with the Cleveland Guardians, with Emerson Hancock getting nine strikeouts to salvage the series.[48][49] After Cal Raleigh's walk-off single, the Mariners lost the final two games of their series against the New York Yankees.[50][51] Following the opening homestand, the team signed top prospect shortstop Colt Emerson to an eight-year, $95 million contract extension, though he remained in the minors.[52] Incumbent shortstop J. P. Crawford came off the injured list.[53]
Seattle offensive struggles continued on their first road trip.[54] After defeating the Anaheim Angels on April 3, the team lost five consecutive games. Right fielder Jo Adell robbed three potential Mariners home runs to preserve a 1–0 Angels win on April 4.[55] The Texas Rangers then swept Seattle.[56] In Texas, outfielder Víctor Robles went on the injured list, replaced by Connor Joe, who made a costly fielding error and was hitless in his Mariners debut.[57][58]

The Mariners ended their losing streak by sweeping a four-game series against the Houston Astros, scoring six or more runs in each game.[59][60] Prior to the first game, the Mariners unveiled a statue of Ichiro Suzuki, with the statue's bat breaking during the ceremony.[61] In the second game, Crawford tied a franchise record with his eighth walk-off hit.[60] Cleanup hitter Josh Naylor hit his first two home runs of the season on April 13 to seal the sweep.[59][62]
The Mariners began another losing streak with their next road game. The San Diego Padres swept the Mariners, taking a lead in the Vedder Cup.[63] Closer Andrés Muñoz blew a four-run lead in the second game, a 7–6 walk-off loss on April 15, with José A. Ferrer taking a blown save.[64] The losing streak reached four games with a shutout home loss to the Rangers before the Mariners won on 7–3 on April 18, with Muñoz earning a one-out save with a game-ending bases loaded strikeout.[65] The Mariners split their homestand, winning two games against the Rangers and one against the Athletics, with the final win coming on a Naylor walk-off single.[66] Reliever Casey Legumina, after allowing three runs and taking a loss on April 20, was designated for assignment then traded to the Tampa Bay Rays.[67]
The Mariners then swept the St. Louis Cardinals in St. Louis.[68] Will Wilson homered in his first at bat with the Mariners in the first game of the series.[69] After losing a rain delayed game to open a series against the Minnesota Twins,[70] Seattle won the final two games, with Julio Rodriguez's first three-double game on April 28[71][72] and three RBI by Cole Young the next day.[73] Reliever Matt Brash left the final game of the series after throwing two pitches and went on the injured list with a lat injury.[74]
May

The Kansas City Royals swept the Mariners in Seattle to open May, spoiling Randy Johnson's number retirement as well as a 14-strikeout, no-walk performance by Emerson Hancock on May 2.[75][76] Hancock's strikeout total was the most by an MLB starter since teammate George Kirby struck out 14 in September 2025.[77] After the series, reliever Gabe Speier went on the injured list (IL) with shoulder inflammation.[78] Seattle then dealt the Atlanta Braves their first series loss of the year. Logan Gilbert allowed four solo home runs in the opener, but Luke Raley and J. P. Crawford hit multi-run homers for the comeback win.[79] Bryan Woo, after allowing 13 runs over his previous two starts, threw six shutout innings to close out the series.[80]
Raley hit two home runs, driving in seven runs to power a 12–8 win over the Chicago White Sox in Chicago.[81] However, Seattle lost the last two games of the series, with Eduard Bazardo allowing two runs in the series finale and the team unable to score after loading the bases with no outs in the ninth inning.[82] Seattle then won three out of four games in Houston, with Seattle besting Astros rookie Tatsuya Imai in his second consecutive start facing Seattle.[83] Cal Raleigh, after enduring an 0-for-36 slump, showered with his uniform on, then got two hits in the win on May 12.[84] However, the Mariners' nine-game winning streak over Houston ended with a Zach Cole 10th inning walk-off single the next game, spoiling Bryce Miller's first start of the season.[85][86] After the series, Raleigh went on the IL for the first time in his career, dealing with an oblique muscle strain. Catcher Jhonny Pereda replaced him on the roster.[87]
The San Diego Padres then swept the Mariners at T-Mobile Park, winning all six Vedder Cup games.[88] Seattle promoted top prospect Colt Emerson on May 17, with Brendan Donovan returning to the IL 10 days after returning from his first IL stint.[89] The Mariners then won two out of three games against the White Sox, with Woo throwing six scoreless innings and Emerson hitting a home run for his first MLB hit in the opening game.[90] In the second game, the Mariners deployed a "piggyback" approach, with Luis Castillo making his first regular season relief appearance following five hitless innings by Miller.[91] Seventh inning solo home runs from Pereda, hitting his first MLB dinger, and Randy Arozarena helped the Mariners win the final game of the series. Matt Brash, in his return from the IL, earned the win.[92][93][94] After the series, Víctor Robles returned from the IL, with Connor Joe returning to the minors.[95]
For the second time in May, the Mariners struggled against the Royals. After Seattle won the first game of the series in Kansas City on a Mitch Garver two-run home run,[96] Stephen Kolek threw a shutout.[97] Woo failed to escape the fifth inning in the final game of the series.[98]
Starting with a series in West Sacramento, California, the Mariners then began an eight-game winning streak that vaulted them above .500 for the first time since March and into first place in the AL West for the first time all season.[99][100] The Mariners swept the Athletics, scoring nine runs twice.[99] Returning home, the Mariners then swept the Arizona Diamondbacks.[101] Speier returned from the IL in West Sacramento, with Nick Davila sent down to the minors.[102] After blowing a 5–1 lead, the Mariners won in 10 innings in the first game of the series.[103] Following another scoreless home start from Woo,[104] the Mariners again needed 10 innings to beat Arizona to finish the sweep, with Robles breaking his bat on a walk-off single.[101]
Julio Rodríguez, usually a slow starter, hit 10 home runs in May, the most in any month in his career.[104] The Mariners starting rotation, with Miller returning, increased to six pitchers, with Castillo and Miller using the "piggyback" twice.[105] Injuries to Raleigh, Donovan, Brash, and Speier opened roster spots for Pereda, Joe, Josh Simpson, and Robinson Ortiz.[106] Emerson and relievers Davila, Alex Hoppe, and Domingo González all made their MLB debuts during the month.[107]
June
The Mariners won their first two games in June against the New York Mets, extending their winning streak to eight games.[100] In the first game, Cole Young hit a walk-off single for the team's third extra-inning win in four games.[108] New York snapped the winning streak on June 3, with George Kirby losing his third consecutive decision.[109]
Seattle began their longest road trip of the season dropping two out of three games to the Detroit Tigers. In their first meeting since the 2025 AL Division Series, Kerry Carpenter homered off Bryan Woo to power Detroit to the win.[110] Seattle won the middle game of the series with another scoreless Bryce Miller start.[111] Closer Andrés Muñoz blew his fifth save of the season in the final game at Comerica Park.[112] Seattle then split a four game series against the Baltimore Orioles after winning the first two games. Josh Naylor hit a go-ahead grand slam in the first game, a 6–3 win.[113]In the second game, Nick Davila pitched the 10th inning to earn his first MLB save.[114] The win extended Seattle's AL West lead to three games, the largest of the season. Baltimore scored seven runs to win each of the final two games of the series.[115] Miller threw a career-high eight innings to win the opening game against the Washington Nationals, with Dominic Canzone hitting a home run and a triple. During the game, Randy Arozarena injured his left hamstring, going on the injured list several days later.[116][117] After that 10–2 win, the Mariners failed to score more than three runs in a game for 13 consecutive games, which matched a franchise record and was the longest such streak of offensive futility in MLB since 2016.[115][118][119] The streak began with two lopsided losses at Nationals Park.[120]
The Mariners returned to Seattle to face the Orioles, scoring three runs in each game, which was enough to win two out of three games.[115] Cal Raleigh returned from the injured list and hit a two-run single to win the first game, with Logan Gilbert getting a season-high 10 strikeouts.[121] The Mariners added minor leaguer Curtis Washington Jr., who was batting .190 for the Everett AquaSox, to the active roster for the game to replace Arozarena.[122] Washington became a phantom ballplayer when he was sent down the next day, replaced by Connor Joe.[123] Despite having a quality start, Kirby took his fifth consecutive loss in the second game against Baltimore.[124] Woo continued his scoreless streak at home, pitching innings to win the final game of the series.[125] Facing three left-handed Boston Red Sox starters,[126] the Mariners' offense still struggled to score. Ranger Suárez, Connelly Early, and Payton Tolle all threw quality starts, with the Mariners winning only the final game of the series thanks to a one-run, 6+1⁄3 inning start from Gilbert on June 21.[127][128] Gilbert was named the AL Player of the Week for his performances against Boston and Baltimore, allowing two runs in 13+1⁄3 innings pitched with 18 strikeouts.[129]
The Mariners, scoring three runs for the second consecutive game, won the opening game against the Pittsburgh Pirates, with Pittsburgh-native Cole Young hitting a go-ahead home run in his first game at PNC Park.[130] The Mariners mustered one run in each of the final two games of the series, getting blown out 11–1 in the second game, their most lopsided loss of the season.[115][131] Ohio native Colt Emerson hit a home run in his first game at Progessive Field to power a series-opening win against the Cleveland Guardians.[132] Cleveland won the next two games, though the Mariners scored five runs in the final game, ending their streak of not exceeding three runs in a game. The loss, precipitated by a bullpen collapse in the eighth inning, dropped the Mariners into second place in the AL West for the first time since late May.[133][134]
The Mariners ended June with two comfortable home wins against the Los Angeles Angels. Young hit two home runs and Kirby pitched eight innings in the opening game.[135] In the second game, Woo set a franchise record with 32+1⁄3 consecutive scoreless innings pitched at home, which dated back to May 6, before Eduard Bazardo allowed an inherited runner to score for the Angels.[136]
Dominic Canzone led the Mariners offensively, batting .314 with six home runs.[137] He began batting higher in the batting order and facing more left-handed pitchers.[138] Raleigh, in his return from injury, continued to bat under .200 but led the team in walks.[137][139] Gilbert and Miller led Mariners pitchers, with each topping 30 strikeouts with an ERA under 3.00 as the Mariners continued to use a six-man starting rotation, all of whom had at least one quality start.[140] The Mariners ended June one loss behind the Texas Rangers in the AL West and in the final AL Wild Card spot.[141][119]
July
The Mariners lost their playoff position and dropped below .500 in July, playing particularly poorly on the road, going 3–10.[115]
Pre-All-Star break
The Mariners finished the sweep of the Angels on July 1 to move into a tie for first place in the division. However, center fielder Julio Rodríguez left the game after a Nolan Schanuel throw hit him in the back of his helmet. Rodríguez went on the seven-day concussion injured list. Replacement center fielder Víctor Robles also left the game.[142][143] The Toronto Blue Jays, behind a strong Dylan Cease start, won the first game in the 2025 ALCS rematch, 2–0. Randy Arozarena lost both of Seattle's Automated Ball-Strike (ABS) System challenges in his first-inning at bat.[144][145] Before the game, the U.S. men's national soccer team gathered on the field and head coach Mauricio Pochettino threw out the first pitch to manager Dan Wilson.[146][147] After the scoreless loss, Seattle shut out Toronto the next two games. Arozarena hit a grand slam, Cal Raleigh hit a three-run home run, and Logan Gilbert pitched 7+1⁄3 innings with seven strikeouts on July 4.[148] In the final game of the series, Mitch Garver hit a two-run home run and Emerson Hancock pitched seven scoreless innings.[149] The Mariners had six different pitchers throw a quality start in consecutive games, the first time that happened in MLB since the Houston Astros in September 2023.[150] On July 5, Arozarena was named to the MLB All-Star Game, his second consecutive selection.[151]
The Mariners lost the first five games of their final road trip before the All-Star break. They lost in 10 innings against the Miami Marlins on July 7. Gabe Speier allowed a game-tying home run to Heriberto Hernández. In the 10th inning, Weston Wilson made a base running error for the Mariners, then Jakob Marsee had a walk-off hit. The Mariners were shut out in the second game, with Cole Young not using an ABS challenge on a called strikeout to end the game.[152] Arozarena and Dominic Canzone homered in an 8–4 loss on July 9 to finish the sweep.[153] Traveling north, the Mariners lost to the Tampa Bay Rays, as Luis Castillo allows three home runs on July 10.[154] Gilbert picked up his 1,000th career strikeout, the fifth player in franchise history to do so, in a 6–1 loss.[155] The Mariners won the final game before the break, with Wilson and Arozarena homering. However, Hancock was hit on his throwing hand by a Yandy Díaz batted ball on the first pitch he threw and was removed in the second inning.[156] The losing road trip dropped the Mariners below .500 and below the Texas Rangers in the AL West at the All-Star break.[157] Arozarena had one single in two at bats in the All-Star Game.[158]
Post-All-Star break
The Mariners returned home, losing 7–0 to the San Francisco Giants on July 17 before winning the final two games of the series.[115] The next day, Raleigh hit a three-run home run off Giants ace Logan Webb to tie the game, then Rodríguez, in his return from the concussion injured list, hit a walk-off sacrifice fly in the 10th inning.[159][160] Gilbert struck out 10 to top former Mariner Robbie Ray in the rubber match, as Luke Raley and Young homered off reliever Adrian Houser.[161] Seattle's winning streak reached three as George Kirby pitched six scoreless innings against the Cincinnati Reds.[162] Manager Terry Francona intentionally walked Canzone to have left-handed reliever and former Mariner Caleb Ferguson face the switch-hitting Raleigh, who knocked a grand slam.[163] Seattle lost the final games of the homestand. Chase Burns pitched five scoreless innings on July 21,[164] then Sal Stewart hit a go-ahead three-run home run off Eduard Bazardo to win the final game, spoiling Hancock's quality start.[165]
The Mariners traveled to Arlington, trailing the Texas Rangers by half a game, then lost three of four games.[115] In the first game, Bazardo allowed two inherited runners from Bryce Miller to score. In the game, Joc Pederson of the Rangers notched his 1,000th career hit.[166] Bryan Woo then had another poor road start, allowing five runs in the first two innings as Nathan Eovaldi gave up one run in seven innings.[167] The Mariners' lone win in the series came on a Canzone go-ahead three-run home run off Cole Winn followed immediately by an Arozarena home run in the seventh inning on July 26.[168] Kirby allowed seven runs in four innings the next day as Texas took the series.[169] The Mariners mustered one win in a series against the defending World Series champion Los Angeles Dodgers, with Canzone hitting two home runs, including a two-run home run off Alex Vesia in the eighth inning, to win the first game. Rob Refsnyder returned from the injured list and also homered.[170] The next game, Andy Pages had three hits, including a home run, off Hancock.[171] Dalton Rushing and former Mariner Teoscar Hernández homered and Roki Sasaki allowed two runs as the Dodgers took the series.[172]
The Mariners returned home to lose the final game of July to the Minnesota Twins, extending their losing streak to three games. José A. Ferrer and Bazardo both allowed home runs and Luke Keaschall hit a go-ahead double off Ferrer as the bullpen blew the lead.[173]
Arozarena, Canzone, and Young led the Mariners offensively in July.[174] Canzone regularly hit third in the batting order and faced more left-handed pitchers.[175][176] Josh Naylor led the team with a .274 batting average and six stolen bases but hit no home runs and had four RBI.[174] Refsnyder returned to the team in late July, with Miles Mastrobuoni and Buddy Kennedy leaving the roster. J. P. Crawford went on the injured list with left wrist inflammation at the end of the month.[177][178][179]
August
After losing the opening game of the series to the Twins, the Mariners had two walk-off wins. On August 1, the Mariners capitalized on a defensive miscue by Twins first baseman Royce Lewis during Cal Raleigh's ninth-inning ground out to first base, allowing Randy Arozarena to score the winning run in a 4–3 victory.[180] That day, the Mariners placed Luke Raley on the 10-day injured list for a left forearm strain; it was later announced he would undergo season-ending surgery on his flexor tendon.[181][182] That night, the Mariners traded Luis Castillo to the Chicago White Sox for relief pitcher Seranthony Domínguez and minor leaguers Nolan Jones and Boston Smith.[183][184] While there were trade rumors involving George Kirby and Arozarena, president of baseball operations (POBO) Jerry Dipoto said that the Mariners never engaged in advanced negotiations for either.[185][186][187] The Mariners won the next day, taking an early lead backed by a Josh Naylor double, an RBI single Cole Young (who had four hits), and a Raleigh home run. Though Kirby pitched 7 scoreless innings, the bullpen gave up the lead when Eduard Bazardo and José A. Ferrer gave up two home runs, followed by Andrés Muñoz giving up a game-tying home run to Luke Keaschall. Muñoz received the win however, after Colt Emerson hit a walk-off single for a 7–6 victory.[188][189]
On August 3, the Mariners completed their trade deadline by acquiring outfielder Taylor Ward from the Baltimore Orioles for reliever Alex Hoppe and minor leaguers Brock Moore, and Harrison Kreiling.[190][191] Before the series against the Detroit Tigers, the Mariners released Mitch Garver and Rob Refsnyder to clear roster space for Ward and Brendan Donovan, who returned from the injured list.[192][193] The Mariners were shut out 8–0 against the Tigers on August 4 after seven scoreless innings by Troy Melton.[194] On August 5, the Mariners won 4–2 after Bryan Woo pitched seven scoreless innings and Julio Rodríguez and Emerson homered.[195][196] In the 7th inning, Raleigh was hit by pitch from Enmanuel De Jesus in the lower stomach. The next inning, Gabe Speier hit the third batter, Gleyber Torres. Both benches cleared and Speier and manager Dan Wilson were ejected.[197] Both were suspended; Speier for three games (which he appealed) while Wilson was suspended for one game.[198][199] The Mariners lost the series finale 11–0, shutout from seven innings by Framber Valdez alongside home runs by Dillon Dingler (having one in every game of the series) and All-Star rookie Kevin McGonigle.[200][201]
The Mariners celebrated 50 seasons of baseball in the next series against the Tampa Bay Rays, though they lost all three games.[202][203] On August 7, the Mariners lost 2–1 after a pitchers' duel. Drew Rasmussen threw seven shutout innings for Tampa Bay, while Rodríguez provided Seattle's only run with a solo home run in the ninth inning.[204][205] After the game, the Mariners held an alumni Home Run Derby.[206] Stefen Romero won the contest over current bullpen coach Austin Nola in the finals after participation by Hall of Famer Ichiro Suzuki, All-Star Mike Cameron, Bucky Jacobsen, and broadcasters Ryan Rowland-Smith and Ryon Healy.[207][208] Before the second game, the Mariners announced the 50 Greatest Mariners Players, also honoring former manager Lou Piniella.[209][210] The team announced that retiring long-time broadcaster Rick Rizzs would be inducted into the Mariners Hall of Fame in 2027.[211][212] The Mariners lost another low-scoring game, with Michael Rucker allowing two decisive runs in the sixth inning. Naylor hit two home runs for the Mariners' only scoring.[213] The Rays completed the sweep with Ward scoring the lone run with a first-inning triple. Ian Seymour and three relievers shut down the Mariners, and Liam Hicks hit a bases-loaded double off Ferrer.[214]
The Mariners lost the first two games of the three-game series against the Yankees.[215][216] On August 13, they won the final game 1–0 after a first-inning home run by Weston Wilson, six scoreless innings by Gilbert, and four successful ABS overturns by catcher Jhonny Pereda.[217] After losing the first game of the series against the Astros 7–10, the Mariners won the next two 10–5 and 3–2, winning the series. In the first win on August 15, the Mariners were backed by Cole Young and Brendan Donovan, both having 3 hits with Young hitting a three-run home run in the 9th inning.[218] The second was backed by homers from Arozarena and Raleigh and 6 innings by Woo.[219] The Mariners suffered the most lopsided loss in franchise history, losing to the Milwaukee Brewers 22–0 on August 18.[220][221][222] Although they rebounded to win the following game 7–5, it was their only win of the three-game series.[223][224] On August 21, the Mariners beat the Chicago Cubs 6–5 on a walk-off single by Leo Rivas in the 10th inning.[225] The next day, the Mariners beat the Cubs again, this time 5–4 from a walk-off by Arozarena after he hit his second home run of the game (having 3 hits overall) in the 9th inning.[226] However, they suffered their biggest home loss in franchise history in the final game of the series, falling 19–2.[227][228]

Top pitching prospects Kade Anderson and Ryan Sloan were selected for the All-Star Futures Game.[237] Anderson and Lázaro Montes were named the Texas League pitcher and player of the month, respectively, for June.[238] Anderson had a 1.06 ERA in 18 starts in Double-A, the second-lowest ERA by a pitcher with at least 90 innings pitched at Double-A and/or Triple-A since 1963.[239]
During the 2026 MLB draft, the team selected infielder Ace Reese in the first round[240] and outfielder Jake Brown, Anderson's former college teammate, in the second round.[241][242]
