Overview
- Players and coaches from the Chicago Cubs and Arizona Diamondbacks had a loud verbal exchange during the fifth inning of the game on Monday after Arizona accused Cubs third‑base coach Quintin Berry of relaying Merrill Kelly’s changeup.
- Kelly publicly called the coach’s involvement 'bush league' and said the team believed the Cubs were signaling his changeup to left‑handed hitters.
- Major League Baseball clarified that coaches may relay signs from inside the designated coaching box, and Diamondbacks manager Torey Lovullo spoke with MLB’s Michael Hill and apologized to Cubs manager Craig Counsell the next day.
- Cubs bench coach Ryan Flaherty and Diamondbacks bench coach Jeff Bannister later met with Berry at the ballpark and publicly reconciled with a handshake and hug.
- The Diamondbacks have acknowledged that Kelly was tipping his changeup and are working to fix that issue because fixing the tell is the most direct way to remove the advantage and protect their late‑season playoff chances.
