In September 2010, Volstad was involved in a bench clearing brawl against the Washington Nationals. In the day's previous game, the Nationals' Nyjer Morgan intentionally ran into Marlins' catcher Brett Hayes on a play at home plate where Morgan was called out. Hayes separated his shoulder and it was determined later that night that he would miss the remainder of the season. In Morgan's first at-bat, Volstad threw at Morgan, hitting him. Morgan proceeded to steal two bases when the Marlins had an almost double digit lead, breaking an unwritten rule of ethics in the game. Offended by Morgan once again, Volstad threw another pitch at Morgan in his next at-bat, with it going behind Morgan's back. Morgan quickly charged the mound, despite the fact that Volstad stood nearly a foot taller than him. Morgan's punch connected, and Morgan was promptly knocked to the ground by Marlins' first baseman Gaby Sánchez, resulting in the bench-clearing brawl. After the game, Volstad sported a shiner from the Morgan punch. Volstad was suspended for 6 games because of the incident.
