On the field, Boone made plenty of rookie mistakes. Without the benefit of a veteran bench coach, Boone’s inexperience showed, particularly in his bullpen usage. That blew up in the Yankees’ collective faces in Game 3 of the ALDS. Perhaps because of a pregame plan handed down from the baseball operations department, or a miscommunication with Luis Severino, or his own hesitancy to pull a star pitcher, Boone inexplicably sent the righty back out for a fourth inning. It was a cringe-worthy moment, considering Severino had already started to struggle, and it led to the most lopsided loss in the Yankees’ storied playoff history.
