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

His expected wOBA is .300, which is .015 below the league average of .315, and he has enough plate appearances for that number to be reliable. His actual wOBA is .297, tracking right with it, so there is no bad-luck story dragging the line down. The contact quality is the culprit: his barrel rate is 1.9% against a league average of 8.0%, his hard-hit rate is five points below league, and his exit velocity sits 1.1 mph under the average — all on stable samples. The striking contrast is that his strikeout rate and swing decisions are fine, yet the weak contact caps his ceiling. The market might still see a middle infielder with a decent walk rate, but the bat has not produced and there is no luck about to flip. Sell. 1 HR / 22 R / 20 RBI / 6 SB / .252 AVG: a ROS that reads as a waiver-floor hold, not a rotational asset.
