Vierling is a hold — league-average skill, no luck distortion.

His expected wOBA is .304, just .011 below the league average of .315, and he has enough plate appearances for that number to be reliable. His actual wOBA is .259, 56 points lower, but the expected mark is what his contact quality has earned — his .304 expected wOBA sits close to league and the gap between the two lines is the contact he's made, not a cold streak that's about to break. The wrinkle: his expected wOBA has been stepping down across the sample, so the skill is trending toward the lower line rather than the higher one. His strikeout rate of 16.8% is well below league average, so he puts the ball in play. Nothing here is unstable enough to force a move. Hold.
