Merrill Kelly

AZ·P
data as of June 3, 2026·week 10

Kelly is a sell — the numbers are ugly and stable.

His expected ERA is 7.29 — more than three runs above league average — and he has faced 234 batters, enough to trust that number. His actual line tracks with it: no bad-luck story hides the skill. Contact quality against him is terrible: 16.4% barrels allowed (double the league average) and 44.1% hard-hit, both stable at 177 batted balls. His strikeout rate has been stepping down across the sample, now at 14.1% — eight points below league, which limits his ceiling severely. The walk rate is slightly elevated. There is no luck mechanism to blame and no skill to fall back on. This is the level he is at. Sell.
