Arraez is a hold — near average, with one loose thread.

His expected wOBA is .305, ten points under the league average of .315, and 595 plate appearances is well past where that number becomes reliable. The reason it sits below league is contact quality: 86.3 mph average exit velocity, a 19.0% hard-hit rate, and 1.1% barrels, all far under league, on 536 batted balls. This is a player who puts the bat on everything — a 4.4% strikeout rate, a 3.8% swinging-strike rate — but does not drive the ball. His actual wOBA of .335 is helped by a .317 BABIP against a league mark of .295, and 536 balls in play is short of the roughly 800 needed for BABIP to be reliable, so expect some of that average to pull back. His expected wOBA has been drifting down across the sample. Nothing here is unstable enough to act on in either direction. Hold. 0 HR / 5 R / 4 RBI / 1 SB is empty-category filler; the .298 AVG is the asset, and deep-league-only holds still need it.
