Despite the injury, Grove was selected in the second round of the 2018 MLB draft by the Los Angeles Dodgers, though he did not play in a professional game until 2019 when he made 21 starts for the Rancho Cucamonga Quakes.[1][3] The 2020 season minor league season was cancelled because of the COVID-19 pandemic, but Grove was added to the player pool and trained at the alternate site at the University of Southern California.[4] He played in 21 games for the Tulsa Drillers in 2021, where he was 1–4 with a 7.86 ERA in 21 games (19 starts).[3]
On November 19, 2021, the Dodgers added Grove to their 40-man roster to protect him from the Rule 5 draft.[5] After beginning the 2022 season with Tulsa, Grove was promoted to the major leagues to make his debut as the starting pitcher against the Philadelphia Phillies on May 15, 2022.[6] He pitched 3+2⁄3 innings in his debut, allowing four hits while walking three and striking out three. Four unearned runs scored off him and his first MLB strikeout was of Alec Bohm.[7] On September 25, Grove picked up his first major league win against the St. Louis Cardinals.[8] He made seven appearances in the majors, making six starts with one relief appearance. He allowed 15 earned runs in 29+1⁄3 innings for a 4.60 ERA.[9] He also pitched in 19 games (17 starts) in the minors between Tulsa and the Triple-A Oklahoma City Dodgers, with a 1–5 record and 3.79 ERA.[3]
In 2023, he pitched in 18 games in the majors, with 12 starts, and a 2–3 record with 6.13 ERA and 73 strikeouts.[9] In 2024, Grove became a full-time relief pitcher, making 39 appearances in the majors with a 4–4 record, 55 strikeouts, and a 5.12 ERA[9] He also pitched 10 games for the Triple-A Oklahoma City Baseball Club, posting a 2–0 record and 1.59 ERA with 11 strikeouts across 11+1⁄3 innings pitched.[3] Grove pitched in one game in the NLDS, recording one strikeout and allowing a home run.[10] He suffered a shoulder injury in that game and was removed from the postseason roster.[11]
Grove underwent right shoulder labrum surgery during spring training before the 2025 season, and it was announced that he would miss the entire season while recovering.[12] He was removed from the 40-man roster and sent outright to Triple-A Oklahoma City on November 6, 2025.[13] Grove elected free agency the same day.[14]
Tampa Bay Rays
On April 14, 2026, Grove signed a major league contract with the Tampa Bay Rays; he was subsequently placed on the 15-day in injured list due to his continued recovery from surgery.[15]
