2024 Fantasy Outlook
A sixth-round pick in 2021, Woo debuted in June to little fanfare. He ended up taking the ball 18 times for the Mariners around a stint on the injured list with right forearm inflammation, and Woo pitched well enough to position himself as the club's fifth starter -- at least tentatively. Woo throws the kitchen sink at opposing hitters (four-seamer, sinker, cutter, slider, changeup) and it's all helped by the extension he gets on his throws. His strikeout rate was relatively modest at 25.1%, but his minor-league K rates suggest there is room for growth in that department. He was bit by the long ball occasionally, and it's possible Seattle brings in another starter to two this winter to bump Woo down the depth chart. He's not assured of a starting role to begin 2024, but Woo will likely be needed for a good number of starts either way. Read Past Outlooks

Battling forearm tightness
PSeattle Mariners
Forearm
May 10, 2024
Woo said after Friday's 8-1 win over the Athletics that he has been dealing with tightness in his forearm, Ryan Divish of The Seattle Times reports.
ANALYSIS
Woo acknowledged that he experienced forearm tightness during his recent minor-league rehab outings, but the issue didn't prevent the Mariners from activating him from the 15-day injured list Friday ahead of his 2024 MLB debut. The right-hander struck out three and allowed just one hit and one walk over 4.1 innings Friday, but he ended up being pulled as a precaution after the forearm tightness cropped up again. Mariners manager Scott Servais said he expects Woo to be fine, and for now, the expectation is that the 24-year-old will make his next start, which is expected to come Wednesday against Kansas City.
