Rocchio is a sell — the contact is light and the line is honest.

He is averaging 87.0 mph off the bat, two mph below the league average of 89.0, and his 30.0% hard-hit rate sits ten points under league. That contact profile has had 458 batted balls to settle in, so it is past the point where it becomes reliable. His expected wOBA of .294 is 21 points below league average, and his actual wOBA of .311 is close enough that there is no bad-luck story pulling the line down. His strikeout rate is low at 14.4%, which keeps him in the lineup, but it does not create power. His expected wOBA has been stepping down across the sample, so the trend points the same direction as the level. What you see is what he is. Sell. A 0 HR / 0 R / 0 RBI / 0 SB / .000 AVG line is waiver-wire material — streaming-only, not a stash.
