May is a sell — his expected ERA says he's below league.

His expected ERA is 4.45, a third of a run above league average, and he has faced enough batters for that number to be reliable. There is no luck story underneath it: he strikes out 23.2% of batters and walks 8.1%, both right at league, so the run prevention is not being hidden by sequencing or an outlier walk rate. Batters are squaring him up, with a 44.3% hard-hit rate allowed against a 40% league mark, while his whiff rate sits exactly at league (10.9%). The xERA has stepped up across the sample rather than settled down — this is the direction his season is traveling, not a blip. The strikeouts and velocity say there is a real arm here, but the contact he allows keeps him from converting it. Sell. Sell into a 0 K / 4.33 ERA / 1.35 WHIP line — waiver-wire fodder, not a hold.
