Three days after making the first relief appearance of his MLB career, right-hander Logan Gilbert will start on the mound for the Seattle Mariners in Game 2 of the American League Championship Series on Monday in Toronto.

Mariners manager Dan Wilson announced Gilbert as the Game 2 starter after Seattle opened the ALCS with a 3-1 win over the Blue Jays on Sunday night.

Gilbert started Game 3 of the ALDS last Tuesday, throwing six strong innings in the Mariners’ 8-4 win over the Detroit Tigers. The 28-year-old allowed only one run and four hits, while recording seven strikeouts and no walks on 85 pitches.

Gilbert then threw two-plus scoreless innings out of the bullpen in Seattle’s marathon 3-2, 15-inning victory over the Tigers in Friday night’s deciding Game 5 of the ALDS. He worked a 1-2-3 frame in the 10th, worked around a leadoff single in the 11th and then was removed in the 12th after allowing the first two batters to reach base. He struck out two and allowed three hits in the 34-pitch relief stint.

It was Gilbert’s first relief appearance in 149 combined regular-season and postseason outings. The last time he came out of the bullpen was back in 2017, when he was pitching for Stetson University.

“The outing the other night in the 15-inning game was really a good side day for him,” Wilson said. “The way we’re looking at it is he took a side session in the game with 40,000-plus people there. He’s ready to go. He’s excited. He wants the ball. So it’ll be Logan tomorrow.”

Gilbert was Seattle’s opening day starter this season after an All-Star campaign in 2024.

Gilbert posted a 3.44 ERA in 25 starts this year, recording 173 strikeouts and 31 walks over 131 innings. He landed on the injured list with a flexor strain in late April, but returned in mid-June and made every start the rest of the way. He finished the regular season on a strong note, posting a 2.30 ERA over his five September outings.
