Montero is a buy — skill is real and stable.

His xERA sits at 3.53, half a run below the league average of 4.1, and he has faced enough batters for that number to be trustworthy. The expected ERA has actually been stepping down across his appearances, while his fastball velocity has inched up — the arsenal is trending in the right direction. His barrel rate allowed (7.4%) and xwOBA allowed (.293) are both below league norms, and his walk rate (5.7%) is well controlled, even if his strikeout rate (16.8%) is below average. Those contact-suppression metrics are stable past their respective thresholds. The skill is real and the sample is sufficient. Buy. 42 K and a 3.53 ERA make Montero a deep-league asset worth acquiring now.
