Jeff Kent vs. Barry Bonds
By the time he came to San Francisco in 1997, Jeff Kent had already developed a reputation as a clubhouse recluse. Things only worsened when he encountered his equal in Barry Bonds. Despite the Giants' World Series appearance that season, a long-standing behind-the-scenes feud between the two became widely public in 2002. The powder keg erupted in a June game when Bonds and Kent became involved in a dugout shoving match that resulted in Kent saying days later, "I want off this team." He eventually got his wish, and signed with the Astros after the season.
