Rocchio is a sell — the contact is short and the line isn't unlucky.

His expected wOBA is .294, and that is .021 below the league average of .315 with enough plate appearances to trust it. There is no bad-luck caveat here: his actual wOBA of .304 tracks right with it, so nothing is dragging his line down that is waiting to come back. The contact quality is where the problem sits. He averages 86.9 mph off the bat, two mph below league, with a 31% hard-hit rate and a 3.1% barrel rate — all well short of league average on samples past the point where these numbers become reliable. The bat does not project to improve, and his expected wOBA has been stepping down as the season goes. There is no floor: Sell. A 0 HR / 5 R / 5 RBI / .234 AVG line is a drop, not a hold — the bat gives nothing in 5x5.
