Montero is a buy — his run prevention is earned, not lucky

His expected ERA is 3.52, .58 below the league average of 4.1, and across 625 batters faced that number is past the point where it becomes reliable — and it is still stepping down. The contact quality backs it up: his expected wOBA allowed is .290 against a league average of .315, his hard-hit rate allowed is 36.4% against 40.0%, and his barrel rate allowed is 7.2% against 8.0%, all on a sample of 475 batted balls that clears the threshold. He is not doing it with strikeouts — 17.1% against a league average of 22.0% — but he does not need to, because he walks just 5.9% of batters. His fastball is averaging 94.3 mph and has been climbing. That profile will keep working. Buy. 0 K stings, but the 3.52 ERA and 1.18 WHIP make him a deep-league asset worth stashing now.
