Peraza is a sell — the bat is below league and trending the wrong way.

His expected wOBA is .271, forty-four points below the league average of .315, and 347 plate appearances is well past the point where that number becomes reliable. His actual wOBA is .275, nearly the same, so nothing on his stat line is being held down by bad luck — the line is the skill. The contact backs it up: 87.1 mph off the bat and a 35.3% hard-hit rate, both below league. The strikeouts make it worse. He strikes out 30% of the time, he swings through 16.7% of pitches, and he chases 38.6% of pitches outside the zone. The xwOBA has been stepping down and the strikeout rate stepping up. There is no floor and no luck to give back. Sell. 0 HR / 4 R / 3 RBI with a .203 AVG is waiver-wire drag — drop him and stream the roster spot.
