Mariners right-hander Bryan Woo made an early exit from tonight’s start, as Woo left the mound after a few warm-up pitches prior to the start of his sixth inning of work. Following the game, M’s manager Dan Wilson told the Seattle Times’ Ryan Divish that Woo was dealing with “a little pec tightness” and would undergo an MRI on Saturday to explore the extent of the injury.
Wilson said that Woo initially told him about the discomfort after the previous inning, so the warm-up pitches were just a precautionary way of testing things before the decision was made to pull Woo from the game. Catching any possible injury early left Wilson hopeful that Woo has avoided something more serious, though more will be known once the tests are complete.
Woo hadn’t shown any indication anything was wrong, as he was masterful in limiting the Astros to just one hit and one walk over five shutout innings. The bullpen kept up the good work in finishing off Seattle’s 4-0 shutout win, which put the Mariners a game ahead of Houston in the AL West standings. The M’s also moved into position for a first-round bye, by dint of winning their season series with the AL Central-leading Tigers. With the playoff push in full swing and the Seattle fans dreaming of October success, losing Woo to the injured list would be a huge setback for the streaking Mariners.
The usually dominant M’s rotation take an overall step backwards this season, but Woo has been a stabilizing force in what has been the best of his three big league seasons. Even before tonight’s gem, Woo had a 3.02 ERA and 26.8% strikeout rate over 181 2/3 innings. A .238 BABIP has certainly added to Woo’s success and helped counter his hard-contact issues, but Woo has helped his own cause with an elite 4.9% walk rate that sits among the league’s best.
Amidst all of the impressive stats, the 186 2/3 innings Woo has now logged may be the most noteworthy, given the injury concerns that plagued the early stages of his career. He was recovering from a Tommy John surgery in his college days when the Mariners made him a sixth-round selection in the 2021 draft, and Woo missed time due to arm injuries in both 2022 and 2023, though he was able to make his MLB debut in the latter season. Elbow inflammation delayed his 2024 debut until May 10, and between that IL stint and a hamstring strain, Woo was limited to 121 1/3 big league frames last year.
