Woo is a buy — the strikeout and walk profile backs the expected ERA

His expected ERA is 3.68, .42 below the league average of 4.10, and he has faced enough batters for it to hold. The discipline numbers underneath are what sell it: he strikes out 24.6% of batters against a 22% league mark and walks just 5.5% against 8%. That gap does not come from balls in play. His xwOBA allowed is .296, with weak contact numbers to match — a 7% barrel rate allowed that sits below league. The fastball has climbed to 96.1 mph, a mile per hour over average, and the velocity is still stepping up. The contact suppression is earned, not sequenced. Buy. The 3.68 ERA and 1.17 WHIP are a deep-league asset worth stashing now before the strikeouts show up.
