Overview
- A heated, verbal exchange broke out between the Chicago Cubs and Arizona Diamondbacks when Arizona accused Cubs third‑base coach Quintin Berry of relaying Merrill Kelly’s pitches from the coaching box.
- Merrill Kelly publicly called the tactic “a little bulls‑t” and said he believed Berry was relaying signals on his changeup while the teams argued on the field.
- Major League Baseball informed Diamondbacks manager Torey Lovullo that coaches may pick up and relay signs from inside the coaching box and Lovullo then called Cubs manager Craig Counsell to apologize.
- The dispute did not turn physical and the Cubs kept a 7‑0 win, but the focus shifted to Arizona fixing the mechanical tell that Kelly acknowledged he was giving away.
- The episode highlights how teams now pair video scouting with in‑person observation to find small edges and how this season’s coaching‑box rules have clarified what coaches may do from their boxes.
