Arnsberg was walking off the mound after talking to starting pitcher Nelson Figueroa when he was ejected by home-plate umpire Paul Schrieber, perhaps for arguing balls and strikes. Arnsberg got in the face of the umpire, bringing Mills out from the dugout.
Mills argued with second-base umpire Joe West, the crew chief, and was eventually given his second ejection of the season. Mills was ejected April 10 against the Marlins after an Astros pitcher hit a batter after both teams had been warned. Mills was later fined and suspended one game.
