Story is a sell — the strikeouts and weak contact are stable.

His expected wOBA is .247, which is .068 below the league average of .315, and he has 263 plate appearances — well past the point where that number becomes reliable. His actual wOBA is .272, slightly above his expected mark, so there is no bad luck dragging the line down. He strikes out 32.7% of the time, against a league average of 22.0%, and he chases 43.9% of pitches outside the zone against a league average of 28.5%. That combination caps whatever floor he might have. His average exit velocity is 87.1 mph and his hard-hit rate is 36.4%, both below league, so the contact is not hiding a better hitter underneath. His expected wOBA has been stepping down across the sample and his strikeout rate has been stepping up. That is a bad trend, not a slump. Sell. 0 HR / 0 R / 0 RBI / 0 SB / .000 AVG makes him a drop — waiver-wire fodder, not a stash.
