SEATTLE — Rain won’t stop Game 5 of the ALDS.
The Detroit Tigers won’t have a rain delay or a postponement for their winner-take-all showdown against the Seattle Mariners on Friday, Oct. 10, at T-Mobile Park, but the weather will decide whether the roof is open or closed.
The game is scheduled to begin at 8:08 p.m. ET – 5:08 p.m. in Seattle.
As of 3 p.m. locally, the roof is closed at T-Mobile Park because it’s raining in Seattle.
For ballparks with retractable roofs, MLB commissioner Rob Manfred — or another designated official — makes all decisions regarding the roof during the postseason, in consultation with the home team and the umpire crew chief. (During the regular season, the home team is responsible for deciding whether or not to begin the game with the roof open or closed.)
In 2025, the Mariners played 10 games with the roof closed during the regular season, going 5-5 (a .500 winning percentage). In their 71 other home games, the Mariners went 46-25 – a .648 winning percentage.
It’s only a 10-game sample, but the Mariners hit .182 with a .602 OPS with the roof closed. With the roof open, the Mariners hit .235 with a .715 OPS.
The rain is expected to stop by first pitch, so the roof could open for Game 5 of the ALDS.
Left-hander Tarik Skubal is starting for the Tigers, opposed by Mariners right-hander George Kirby.
T-Mobile Park is a pitcher-friendly ballpark regardless, but offense gets even worse when the roof is closed. From 2023-25, the stadium had a park factor of 83 for run-scoring with the roof open – 100 is league-average – and a park factor of 77 with it closed.
