Overview
- Chisholm was tossed after arguing a checked‑swing third strike called by home‑plate umpire Adam Hamari, and first‑base crew chief Todd Tichenor ejected him after he slammed his helmet on Sunday.
- He finished 0‑for‑3 with two strikeouts and was replaced in the leadoff spot by Anthony Volpe, a cold substitution that came during a game the Yankees lost 5‑4 in 10 innings and that completed the series sweep by Boston.
- Checked‑swing determinations are decided on the field and are explicitly excluded from MLB instant replay and ABS review, so the call could not be overturned during the game.
- Former Yankee Anthony Rizzo publicly criticized Chisholm’s timing and maturity for getting ejected, and Chisholm left Fenway without speaking to reporters after the loss.
- The incident sharpens scrutiny of Chisholm’s on‑field conduct and June slump and could affect lineup stability and clubhouse dynamics in the days ahead.
