2025 Fantasy Outlook
Woo's 2024 season was an extension of his professional resume: impressive stints disrupted by injury. Woo required an internal brace procedure after his collegiate career in 2021, but reached the majors in 2023 and worked 131.2 innings while skipping over Triple-A in the process. The 2024 season saw him pitch nearly the same amount of innings between the majors and a minor league rehab assignment due to a mid-summer hamstring injury that preceded a forearm discomfort scare in mid-June. Woo throws five different pitches to both lefties and righties, with his sweeper being the deadliest of them all. Woo mainly used the sweeper to neutralize righties (.100 avg, 42 percent whiff rate) while using his changeup to lefties (.186 avg, 21 percent whiff rate), which helped his four-seam fastball (.218 avg, 27 percent whiff rate) play up extremely well. The pieces are here for Woo to take a step forward in 2025 like the other starters around him have recently done, but his health troubles need to get out of the way for him to fully realize his potential.

Earns 13th win
Woo (13-7) earned the win Monday, allowing two runs on three hits and no walks over six innings in a 4-2 victory over St. Louis. He struck out nine.
Analysis
Woo delivered six strong innings Monday, halting a brief two-start stretch of shorter outings after previously going six-plus in each of his first 25 starts. The right-hander has been one of MLB's most reliable arms this season, compiling a 3.02 ERA and 0.95 WHIP across 175.2 innings in 28 starts. While not overpowering with strikeouts (9.1 K/9), his nine punchouts Monday tied a season high, and his elite command (1.7 BB/9) continues to fuel his consistency.

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.

Set for first All-Star appearance
Woo has been selected to participate in the 2025 MLB All-Star Game.
Analysis
Woo posted a 4.21 ERA across 18 starts as a rookie during the 2023 season, but he's improved with each successive season. This is Woo's first All-Star nod, which the right-hander earned by posting a 2.77 ERA through his first 17 starts. He's well on pace to post a sub-3.00 ERA for a second consecutive season.
