Acuña Jr. is a buy — elite contact, skill, no luck.

His expected wOBA is .378, .063 above league average, and it is stable at 236 plate appearances — the production is earned. The contact quality underpinning it is elite and stepping up: hard-hit rate at 43.4%, barrel rate at 13.1%, and exit velocity at 90.1 mph, all above league, all past stabilization. His actual wOBA trails the expected number, suggesting his surface line could actually improve. He walks at a well-above-average clip and strikes out at league average, so the approach is sound. There is no luck story here — the skill is real and the trajectory is up. Buy. 6 HR / 25 R / 19 RBI / 11 SB / .241 AVG is a deep-tier asset; buy if available.
