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

Woo did not factor into the decision in Friday's 6-5 loss to the Angels, allowing four runs on nine hits and two walks over 3.1 innings. He struck out just one.
ANALYSIS
Despite his fastball clocking in at 94.9 mph, up 0.2 mph from his season average, Woo looked rusty in his return from a hamstring injury against an unspectacular Angels lineup. The Seattle right-hander generated only six whiffs on 66 pitches and allowed a career-high nine hits. Even with this poor performance, Woo closes out the first half with a 2.45 ERA, 0.89 WHIP and 29:5 K:BB across 44 innings.
