Tadahito Iguchi
An example of this volatile rivalry is the game played between the White Sox and the Cubs at U.S. Cellular Field on May 20, 2006. White Sox catcher A. J. Pierzynski was running home on a sacrifice fly by center fielder Brian Anderson and smashed into Cubs catcher Michael Barrett, who was blocking home plate. Pierzynski lost his helmet in the collision, and slapped the plate as he rose. Barrett stopped him, and after exchanging a few words, punched Pierzynski in the face, causing a melee to ensue. Brian Anderson and Cubs first baseman John Mabry got involved in a separate confrontation, although Mabry was later determined to be attempting to be a peacemaker. After 10 minutes of conferring following the fight, the umpires ejected Pierzynski, Barrett, Anderson, and Mabry. As Pierzynski entered his dugout, he pumped his arms, causing the soldout crowd at U.S. Cellular Field to erupt in cheers. When play resumed, White Sox second baseman Tadahito Iguchi blasted a grand slam to put the White Sox up 5–0 on their way to a 7–0 win over their crosstown rivals. While other major league cities and metropolitan areas have two teams co-exist, all of the others feature at least one team that began playing there in 1961 or later, whereas the White Sox and Cubs have been competing for their city's fans since 1901.
