Messick is a sell-high — his 2.53 ERA is running on luck.

His ERA is 2.53, but that number is not what his pitching has earned. The gap is his BABIP-against: .264, 31 points below the league average of .295, and that is the flattery keeping runs off the board. BABIP-against needs around 800 balls in play to be reliable, and he has 443 — short of it, so the gap is luck rather than a skill. His expected ERA is 3.03, half a run above the surface, and his xERA has been stepping down across the sample, which means the regression is already in the building blocks. He strikes out 26.1% of batters, above the league's 22%, and his walk rate of 6.8% is below league average. The stuff is good; the ERA is not as good as it looks. Sell high. With 14 K, 3.03 ERA and 1-2 W the rest of the way, sell into the inflated line — standard-league window, not a hold.
