Chances are, you play for Ozzie Guillen, and he's going to hate you at some point. That's sort of what happened with Carlos Lee and the White Sox in 2004, as FanGraphs' Chris Cwik reminds us...
Guillen was critical of Lee’s non-aggressive playing style when he was Lee’s manager with the Chicago White Sox. In a game against the Minnesota Twins, Torii Hunter collided with White Sox catcher Jamie Burke, who had to leave the game with a concussion. Lee had an opportunity to take out the Twins second baseman on a slide late in the game, and did not. After Lee was traded to Milwaukee the following off-season, Guillen cited that moment as one of the reasons for the deal.
We didn't come out here to play tiddlywinks, son.
