URGENT UPDATE: Seattle Mariners’ ace pitcher Bryan Woo has been diagnosed with minor pectoral inflammation, raising concerns just days before the end of the regular season. Manager Dan Wilson announced the news ahead of the Mariners’ critical matchup against the Houston Astros on Saturday.
Woo, who has emerged as the Mariners’ standout pitcher in 2025, reported tightness in his pectoral muscle after throwing five scoreless innings against the Astros on Friday night. The team is now facing uncertainty regarding his status as they push for a postseason spot.
“The MRI revealed some minor inflammation in his pec,” Wilson said. “Really, just kind of a day-to-day thing. We’ll continue to assess him each day, and we’ll know more in the next 24 to 48 hours, depending on how he responds to treatment.”
As of now, there are no definitive plans for Woo’s next scheduled start, nor when he might return to throwing. Wilson noted that Woo is eager to get back on the mound as soon as possible, emphasizing the urgency of the situation as the team fights to maintain their lead in the American League West.
The Mariners currently sit just one game ahead of the Astros, intensifying the pressure on the pitching staff. Woo’s performance has been a key factor in their success this season, boasting a stellar 2.94 ERA across 30 starts and allowing only 137 hits in 186 2/3 innings.
This injury comes at a critical time, as Woo has been a reliable presence in the rotation, even achieving a streak of over six innings in his first 25 starts this season. Wilson praised Woo’s mental fortitude, saying, “This is a guy who has found a great mental space to go to, and that’s been a big key for him.”
The Mariners’ playoff hopes now hinge on Woo’s recovery in the coming days. Fans and analysts alike will be watching closely for updates, as the team’s postseason aspirations may depend on whether Woo can return to form.
With the regular season winding down, the Mariners are hoping for the best as they prepare for potential playoff battles. Stay tuned for more updates as this story develops.
