OPS by game

- Season OPS .693
- Rolling OPS, last 10 games
Each bar is the OPS of one game, oldest on the left. One game is a tiny sample, so a single bar says little about a hitter. Season OPS adds up the 35 games that have a bar, so it can differ from the year-by-year table above.
The rolling line is the last 10 games. It draws only when those games hold at least 30 plate appearances.

A row is one game he played, newest first. A game he did not play has no row, so a log can have fewer rows than the G column above for the same season: a pitcher who batted once shows one hitting row. Season 2026, through Jul 22, 2026.
