Williamson is a sell — below-league skill with no luck to blame.

His expected wOBA is .290, and his actual wOBA is .289 — the line and the skill agree, so nothing is dragging him down. The problem is underneath the surface. He is averaging 87.3 mph off the bat and barreling just 1.5% of his batted balls, both well below league average, and his sample is past the point where this becomes reliable. A 33% hard-hit rate is not a bat that is about to turn. His expected wOBA has been stepping down across his 270 plate appearances, which makes the picture worse, not better. His strikeout rate of 18.9% is fine and there is no BABIP story to soften this. The production is the skill. Sell. 0 HR / 5 R / 5 RBI / 1 SB / .245 AVG is waiver-wire noise — a deep-league streamer at best, so drop him.
