24-Year-Old PitcherSP
Seattle Mariners
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

September 27, 2024
Woo (9-3) allowed three hits and a walk while striking out eight over five shutout innings to earn the win over the Athletics on Friday.
ANALYSIS
Woo kept a scoreless line for the first time since Aug. 14 in his final start of the season. The 24-year-old had seven scoreless starts in 22 outings this season, establishing himself as a high-end starter with an emphasis on elite control in his second major-league campaign. He ends the year with a 2.89 ERA, 0.90 WHIP and 101:13 K:BB over 121.1 innings.
