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

Has no-hitter broken up in seventh
PSeattle Mariners
September 12, 2024
Woo (8-2) picked up the win over the Padres on Wednesday, allowing two runs on two hits and one walk over 6.2 innings while striking out five.
ANALYSIS
Woo had a no-hitter going through the first six frames before giving up a solo homer to Fernando Tatis with one out in the seventh. The right-hander would then be relieved by Troy Taylor with two outs in the inning, though the former would still come away with his third win in his last four decisions. Woo has also produced quality starts in six of his last eight outings while posting a robust 45:4 K:BB over that stretch. On the downside, he's now surrendered at least one long ball in five consecutive starts.
