Peraza is a sell — skill below league with no lucky bounce.

His expected wOBA sits at .283, .032 below league average, and the sample is deep enough to trust that number. His strikeout rate is 29.6% — well above the league 22% — and trending up, which caps his batting average floor. With a walk rate of just 3.6% and a chase rate of 37.6%, both far from league average, he is not getting on base enough to compensate for the whiffs. His actual wOBA of .290 tracks his xwOBA, so there is no bad-luck story to point to. The contact quality metrics — exit velocity, hard-hit rate, barrel rate — are all below or at league average. No luck is dragging him down; the bat is simply below the line and trending the wrong way. Sell. 3 HR / 17 R / 14 RBI / 7 SB / .220 AVG is a drop — a streaming-only rotation piece in deep formats.
