Tensions flared last night when White Sox catcher A.J. Pierzynski came out from behind the plate to accuse White Sox starting pitcher Mark Buehrle of throwing at him. "You've been doing it all night, you piece of sh!t," yelled the combative Pierzynski. "What's your problem?" White Sox batters have been hit the fifth most times in the league this year, but Pierzynski says it's the catchers who have it the worst. "Every inning, it's the same thing. I'm just trying to sit there and call pitches, and these guys are chucking balls right at me at 85 and 95 mph." If it continues, Pierzynski says he may have to start wearing padding and other protection.
