Overview

• Major League Baseball has opened an investigation into whether Braves bench coach Eddie Pérez threatened a beanball by pointing to his head at Yankees infielder Jazz Chisholm Jr. during the sixth inning at Truist Park.
• Pérez denies any threat and says his gesture meant “be smart” after Chisholm signaled upcoming pitches from second base, a tactic allowed without electronic aid.
• Yankees manager Aaron Boone called for MLB to review the exchange, warning that any suggestion of hitting Chisholm in the head would be unacceptable.
• Chisholm has declined to comment on the dispute, which followed a similar sign-relaying episode by the Yankees against the Mariners earlier this month.
• The incident highlights growing tension between baseball’s unwritten codes and formal conduct rules as the league assesses player safety implications.
