Overview

• Woo called his Thursday work at T-Mobile Park a positive step after roughly 25 warmup pitches and a 15-pitch simulated inning against live, non-swinging hitters, though he said he is not yet at full game speed.
• The right-hander is returning from pectoral inflammation that cut short his Sept. 19 start in Houston and noted he was not throwing a week ago but hopes to be in a better spot next week.
• The Mariners have not announced their ALDS rotation and are expected to name at least their Game 1 starter Friday, with the Tigers confirmed as the opponent.
• Given Woo’s All-Star season (15–7, 2.94 ERA), his availability could influence whether Seattle carries an extra arm for later in the best-of-five series and how the bullpen is managed.
• Woo emphasized a controlled ramp-up directed by coaches and trainers, while Bryce Miller has prepared for bullpen duty early with potential to start later if needed, alongside options Logan Gilbert, George Kirby and Luis Castillo.
