Mariners' Bryan Woo Development Emerges as ALDS Nears

Dan Wilson Shares Bryan Woo Injury Update on Wednesday

Woo’s MRI revealed mild inflammation, leading to his skipped start during the final week of the regular season. As the postseason approaches, the Mariners earned a bye through the first round of the playoffs, immediately advancing to the ALDS, which gives Woo an extra five days to recover.

The Mariners shared that Woo would be scheduled to throw a bullpen session on Thursday. Manager Dan Wilson anticipates that Woo will be on the ALDS roster, yet the right-hander must throw at least twice before starting a game, making Thursday a huge first step. Woo would potentially be able to start Game 3 if he accomplishes two throwing sessions without any added discomfort.

“Bryan Woo will throw a bullpen session on Thursday -- though not vs. hitters during a scrimmage. Dan Wilson is still optimistic that Woo will be on their ALDS roster, but it's also likely they'll want to see him throw off a mound at least twice before making a playoff start,” wrote MLB.com’s Daniel Kramer.

The Mariners do feature one of the best rotations in the league with Logan Gilbert, George Kirby and Luis Castillo all being capable playoff starters.

So it is likely the organization will be cautious with Woo even in such a crucial part of the postseason. Woo has emerged as a star for Seattle and he will remain under team control for multiple seasons after 2025.
