Kuhnel is a sell — the strikeouts are gone and the xERA shows it

His xERA is 5.77, a run and two-thirds above the league average of 4.1, and he has faced enough batters for it to be reliable. There is no suppressed BABIP-against or odd sequencing to take the blame — this is the level he's at. The reason is the strikeout rate: 13.9% against a league average of 22%. He struck out 17.6% of batters over his career and the rate has been dropping through this sample. A pitcher who misses that few bats gives hitters 86% of his plate appearances to put the ball in play, and the xwOBA allowed of .362 reflects it. He still throws hard, touching 95.3 mph, but the velocity isn't producing swings and misses. The ERA has nowhere to hide. Sell. Fade the 5.05 ERA and 1.43 WHIP — fringe waiver fodder, not a hold.
