Mike Yastrzemski vs Luis Severino

The Almanac's Take

Yastrzemski gets the platoon edge here as a lefty against Severino's right hand, though his season line gives limited reason for excitement — a .222/.303/.646 clip across 221 PA with a 22.2% strikeout rate. Severino hasn't been sharp either, carrying a 4.16 ERA, 1.47 WHIP, and 4.5 BB/9 over 62.2 innings, so the walk rate at least keeps Yastrzemski's 10.4% BB rate relevant. The 13-PA head-to-head is too thin to mean much — two hits, six strikeouts, and a 75.3 mph average exit velocity are a footnote, not a signal. This one comes down to whether Severino's control issues can offset a batter running below his weight.
