Overview
- Chisholm, who struck out three times in Thursday's 1-0 loss to the Seattle Mariners, has a roughly .216/.296/.391 slash line through mid‑August and has produced 17 home runs in 112 games.
- Data-driven coverage shows a pronounced breakdown against four‑seam fastballs, with a reported -11 Run Value versus that pitch and an average near .187, while opponents have increased fastball usage against him to about 58.9 percent in August.
- His contact problems have translated into high strikeout and whiff rates, with a roughly 35.5 percent K rate since June and Chisholm himself saying he feels he has about a 40 percent whiff rate on pitches.
- Chisholm says he does not know how to fix the slump and rejects sitting as a remedy, while manager Aaron Boone publicly defends his approach and hitting coach James Rowson points to timing and launch‑angle flaws as likely causes.
- The slump carries outsized stakes because Chisholm is a free agent after the season; multiple outlets report the Yankees are unlikely to extend a qualifying offer, making his remaining weeks critical for his market value and New York's offseason choices.
