Kerkering is a hold — league-average, with no luck pulling either way

His expected ERA is 3.87, a touch under the league average of 4.10, and he has faced enough batters for that number to be reliable. The contact numbers back it up rather than cut against it: he gives up hard contact on 31.1% of balls in play, well under the 40.0% league rate, and barrels at 6.1% against 8.0%. His expected wOBA allowed is .303, lower than the .315 league mark, so hitters are not squaring him up. The one crack is the walk rate — 12.7% against a league average of 8.0%, and that is stable at his sample, which is the reason this stays a hold rather than a buy. His expected ERA is trending down across the sample, which argues the skill is settling into place. He is what he looks like right now. Hold. 0 K / 3.81 ERA / 1.42 WHIP keeps him deep-league only — a hold, not a stash, so stream elsewhere and leave him be.
