Trent Thornton
Thornton is a sell-high — the ERA is propped up by BABIP luck.
His ERA is 3.50, half a run better than league average, and the number holding it there will not hold. His BABIP-against is .244, 51 points below the league average of .295. BABIP-against needs around 800 balls in play to be reliable, and he has 140 — that gap is luck, not skill. Strip the noise out and his expected ERA is 5.08, a run and a half worse than what the box score shows. He strikes out 15.3% of batters, well below the league average of 22.0%, and that number is stable — and it is on the way down, sitting under his 21.7% career baseline. Balls in play against him are hard-hit at 44.6%, above league. There is no bat-missing skill here to justify the surface line. Sell high. With 3 K and a 3.70 ERA ROS, this is a deep-league sell before the inflated line corrects.
