Betts is a buy — the skill is earned and the luck is absent

His expected wOBA is .339, .024 above the league average, and 528 plate appearances clears the point where that number becomes reliable. His actual wOBA is .338 — dead even with the expected figure, so nothing on the stat line is being propped up. The strikeout rate is what separates him: 11% against a league average of 22%, with a swinging-strike rate of 5.2% and a chase rate of 20.3%. He is not giving away outs. The contact quality is the one soft spot, with a hard-hit rate of 38% just under league and stepping down across the sample. That has not stopped his expected wOBA from climbing. The production is earned, and the profile behind it is unusually clean. Buy.
