The rivalry turned physical on May 20, 2006, when a brawl broke out during a White Sox-Cubs game at U.S. Cellular Field. In the bottom of the second inning, Brian Anderson of the White Sox hit a sacrifice fly, attempting to score catcher A. J. Pierzynski. Pierzynski collided with Cubs' catcher Michael Barrett. Barrett dropped the ball in the collision and Pierzynski was safe. After slapping home plate in celebration, Pierzynski began to walk away, but Barrett blocked his path and punched him in the jaw. Both benches cleared and a brawl broke out. Umpires debated for 15 minutes before ejecting Pierzynski, Barrett, White Sox outfielder Brian Anderson and Cubs first baseman John Mabry from the game. When play finally resumed, outfielder Scott Podsednik promptly got on base, loading the bases up, and second baseman Tadahito Iguchi cleared them with a grand-slam. The White Sox won the game, 7–0. Michael Barrett was suspended for 10 games, while Brian Anderson was suspended for five and A. J. Pierzynski was fined.
