Arraez is a hold — league-average line, no luck to unwind.

His expected wOBA is .307, eight points under the league average of .315, and the sample is well past the point where that number becomes reliable. His actual wOBA is .331, so he has banked a little good fortune on balls in play, but not a gap that screams regression. The striking thing is how he gets there. His average exit velocity is 86.4 mph against a 89.0 league average, his hard-hit rate is 19.4% against 40.0%, and his barrel rate is 1.2% against 8.0%. He does not miss, though: a 4.3% strikeout rate and a 3.5% swinging-strike rate, both far below league. The expected wOBA has been stepping down across the sample, which says the contact-driven value is softening rather than climbing. Nothing here is unstable enough to force a move in either direction. Hold.
