6. Barry Bonds vs. Jeff Kent
One of the most notorious feuds in baseball history, Bonds and Kent were part of a loaded Giants offense. In 2002, they combined for 83 home runs and 219 RBIs in 2002. However, behind the scenes, all was not well. They had feuded all season but suddenly, it erupted as their cold war turned hot.
It all spilled over when the pair of them started fighting in the dugout in the middle of a game. They tried to brush it off but their relationship was beyond repair. Finally, the Houston Astros came for Kent and he was able to get out of San Francisco. In sum, they weren’t on each other’s Christmas card lists.
