Vierling is a sell — bat below league with no luck.

His expected wOBA is .300, .015 below league average, and he has enough plate appearances for that to be reliable. His actual wOBA is even lower at .262, but that is not bad luck — his BABIP is on the credit list, not here, and his contact quality is plain: 87.6 mph exit velo, 36% hard-hit, 5% barrels, all below league. His strikeout rate is low and his chase rate is up, which frames a hitter who puts the ball in play but not hard. The xwOBA trajectory is stepping down, meaning the trend is away from improvement. There is no luck story to fall back on; this is the level he's at. Sell. 3 HR / 14 R / 21 RBI / 2 SB / .227 AVG: a rotational drop whose numbers match the skills — don't hold.
