He didn't do anything and he was one of many managers that got ejected this week.

CHICAGO -- Major League Baseball suspended Chicago Cubs manager Lou Piniella four games, including the one already served Sunday, for his latest dirt-kicking tirade against an umpire, ESPN Radio 1000 in Chicago is reporting.
Piniella was ejected in the eighth inning of Saturday's 5-3 loss to the Atlanta Braves.
After Angel Pagan was thrown out trying to steal third on a pitch that bounced away from the catcher, Piniella stormed out of the dugout and kicked dirt as he argued and tossed his cap, leading to his ouster by third-base umpire Mark Wegner.
