Carlos Martinez’s Change is Working
In seven innings this season, including six in his start on Sunday, Carlos Martinez has faced 10 right-handed hitters. None of them has reached base and four hitters have struck out. Martinez’s early season dominance against righties is not altogether surprising. Splitting time between the bullpen and the rotation last season, Martinez faced 215 right-handers and struck out more than 30% of them while walking just shy of 7% and giving up only one home run for a 1.94 FIP.
Martinez featured a four-seam and a two-seam sinking fastball with his slider as his out pitch. The slider worked particularly well against righties, generating over a 25% whiff rate, per Brooks Baseball. Of the 87 plate appearances against right-handers that ended on a slider, 41 were strikeouts and five were walks. Martinez had the slider going against the Reds on Sunday, striking out four of the seven right-handed hitters he faced — three of whom he finished off with the slider. Against seven right-handers, Martinez made 31 pitches and threw 25 strikes. As a reminder, here is what the slider looked like against Zach Cozart.
