2018 Japan Series

Daichi Osera started Game 1 for the Carp and Kodai Senga started for the Hawks. Hiroshima scored two runs in the first inning on a home run by Ryosuke Kikuchi and a run batted in (RBI) single by Ryuhei Matsuyama. Osera then went on to strike out six of the first thirteen batters he faced and did not give up a hit until the fifth inning. SoftBank capitalized and scored two in the inning when pinch hitter Alfredo Despaigne drove in a run by singling to second baseman Kikuchi. Kikuchi's throw to first base was off target and resulted in a throwing error that allowed a second runner to score. Both teams had scoring chances during the remainder of the game, including a bases-loaded opportunity in the eleventh inning for the Hawks, but each team's relief pitchers kept the game tied through the twelfth. With the postseason now using the same innings limit as the regular season (after 12 innings instead of 15 in the past), the game ended in a 2–2 tie after twelve innings.^[13] This Japan Series tie game was the first since the 2010 Japan Series and the first to open a Japan Series since 1986.^[14]

In Game 2, the Hawks started Rick van den Hurk. For the second straight game, the Carp scored in the first inning. With no designated hitter, Despaigne was playing left field for only the fifth time all season when leadoff hitter Kosuke Tanaka hit a ball his way. Tanaka was able to stretch a single into a double due to questionable fielding by Despaigne. Tanaka went on to score after a sacrifice bunt moved him to third base and Seiya Suzuki' single drove him home. Hiroshima added to their run total when they scored two unearned runs in the third inning. After a throwing error by Keizo Kawashima allowed runners to safely reach second and third base, Yoshihiro Maru drove one in on a sacrifice fly while the second run scored on an RBI single by Ryuhei Matsuyama. In the fifth inning, the Carp scored twice from a two-run single by Suzuki. Hiroshima starter Kris Johnson allowed only one run on four singles and a walk through seven innings. He struck out seven batters. SoftBank's only run of the night came from a Nobuhiro Matsuda RBI single in the seventh inning.^[15]

With the series moving to Fukuoka for Game 3, the Hawks started Ariel Miranda while the Carp started Aren Kuri. The Hawks scored first; in the fourth inning, Kuri issued two walks and then allowed Akira Nakamura and Kenta Imamiya to each single in a run, giving the Hawks their first lead of the series. After pitching four scoreless innings, Miranda gave up a solo home run to Tomohiro Abe, cutting the lead in half. In the bottom half of the same inning, however, the Hawks scored a run scored off of a throwing error by Alejandro Mejía and scored again after Kuri was taken out of the game. The Carp scored two runs in the next inning, one from a solo home run by Seiya Suzuki. After Akitake Okada retired the first two batters in the bottom half of the inning, three consecutive Hawks' singles gave them another run before Alfredo Despaigne opened up a five-run lead with a three-run home run. A solo home run by Hiroaki Takaya in the seventh inning gave the Hawks just enough runs to fend off a Carp comeback in the eighth inning. Suzuki led off the inning with his second solo home run of the game and then two singles and a walk set the stage for a grand slam by Abe, also his second home run of the game. Hawks reliever Yuito Mori worked a scoreless inning to preserve the win and earn a save.^[16] The win was the Hawks' tenth straight victory at home in the Japan Series, dating back to 2011.^[17] The Carp lost the game with 16 hits, the biggest number of hits made by the losing team in a single match, although it was also the biggest number of hits ever made in a single match by the Carp in the Japan Series history .

The starting pitchers for Game 4 were Nao Higashihama for the Hawks and Yusuke Nomura for the Carp. In the first inning, SoftBank prevented an early lead by Hiroshima when Ryosuke Kikuchi was thrown out at home plate. Kikuchi attempted to score from first base on a double by Yoshihiro Maru, but was thrown out on a relay throw from center field. Higashihama went on to pitch through five innings and allowed only one run on four hits. The sole run scored by the Carp came from a home run in the fourth inning by Suzuki, his third of the series. Nomura was charged with the loss for the Hawks. He lasted 4+1⁄3 innings and gave up a two-run home run to Seiji Uebayashi in the third and allowed Despaigne to hit his second home run of the series in the fourth. The Hawks closed out their scoring with pinch hitter Yuya Hasegawa driving in a run with a hit in the sixth inning. With the win, SoftBank extended their consecutive wins-at-home streak in the Japan Series to eleven,^[18] breaking the previous record of ten held by the 1970–73 Yomiuri Giants.^[19]

Osera and Senga started Game 5, in a rematch of the opening game of the series. For the first time since Game 2, Hiroshima scored first when Tsubasa Aizawa's single scored Ryuhei Matsuyama. SoftBank pulled ahead in the fourth inning on a two-run single by Nakamura and went on to load the bases that same inning, however Osera was able to pitch out of the inning with no further runs being scored. The next inning, Liván Moinelo relieved Senga and promptly gave up a two-run home run to Maru, once again giving the Carp the lead.^[20] The Hawks started the bottom half of the same inning with two singles, one of which was upheld on a replay review. After the runners being bunted over to second and third base, Johnny Hellweg was brought out of the bullpen to relieve Osera. The next batter, Yurisbel Gracial, was hit by pitch to load the bases setting the stage to allow a run to score on a groundout by Yanagita.^[21] Aizawa broke the tie and gave the Carp the lead in the sixth inning but the Hawks tied it up again in the seventh when Akashi hit a solo home run. In the bottom of the tenth inning, Yuki Yanagita won the game with a walk-off home run off of Carp closing pitcher Shota Nakazaki.^[20] The win extended the Hawks' record-setting home winning streak to twelve, and the Pacific League's home winning streak in the Japan Series to fifteen.^[21]

The series shifted back to Hiroshima for Game 6. Rick van den Hurk shut out the Carp for six innings. Tetsuro Nishida drove in a run for SoftBank in the fourth inning with a squeeze bunt that scored Yuki Yanagita. Yurisbel Gracial hit a solo home run in the fifth inning. Relief pitchers Shota Takeda, Shinya Kayama, and Yuito Mori completed the shutout of the Carp, as SoftBank repeated as Japan Series champs. Hawks' catcher Takuya Kai, who set a Japan Series record with six consecutive caught stealings, won the Japan Series Most Valuable Player Award.^[22]
