Woo is a buy — xERA stable, velocity rising.

His expected ERA is 3.51 — 0.59 below league average — and with 424 batters faced that number is trustworthy. His actual ERA is not supplied but xERA tells the story: the run prevention is earned. His strikeout rate is 24.1% against a league 22%, and his walk rate is 4.7% against 8.0% — both stable and well above league averages. Add a 13.2% swinging-strike rate, and the bat-missing ability is real. His fastball velocity actually stepped up across the sample to 95.8 mph, which is nearly two ticks above league average. The hard-hit rate allowed is slightly elevated, but the barrel rate is below league. The skill is real with no luck propping the ERA. Buy. 58 strikeouts, 3.51 ERA, and a 1.15 WHIP make him a deep-league asset worth acquiring now.
