The Almanac's Take

Thin slate today — two games, both reading pitcher-friendly, so the interesting angle is which lineup can do the most damage against a right-hander despite the numbers leaning the wrong way. Painter against Arizona is the sharper spot to watch: five Diamondbacks hitters carry a platoon advantage, even as the lineup's .657 OPS suggests Painter controls the matchup overall — that gap between platoon count and aggregate production is worth tracking batter by batter in the grid below. Bello versus St. Louis is quieter, with only four platoon advantages and a .653 lineup OPS; Urías has 2 hits in 13 PA against him, which is a small sample and nothing more.

How to read this page

Primary read is the lineup strength block — season OPS, lineup K%, and platoon-edge count across the opposing lineup. When enough Statcast PA is on file, the lineup composite vs the pitcher's hand sits alongside it.

Career head-to-head reads as color, not edge. PA count travels with every H2H number on this page so a 4-for-7 sample looks like the small sample it is. The “notable H2H” highlight list is filtered to PA ≥ 10 for that reason.
