Santana is a sell — the expected ERA is a run too high

His expected ERA is 4.69, .59 above the league average of 4.10, and he has faced 250 batters — past the point where that number becomes reliable. Nothing in his profile says the gap is bad luck. His strikeout rate is 19.6%, below the league's 22%, and his walk rate is 10.0%, above the league's 8%. Missing bats less and walking more than average is the wrong combination, and it shows up in the expected wOBA allowed of .331 against a .315 league average. The contact he allows is ordinary, not damaging: hard-hit rate 40.5% and barrel rate 8.1% both sit right at league marks. What is left is a pitcher walking too many and striking out too few. His expected ERA has climbed across the sample. This is the level, not a cold spell. Sell. 0 K / 4.34 ERA / 1.38 WHIP rest-of-season makes him a drop — waiver-tier arm with no strikeout upside.
