Guillen took to Twitter on Wednesday night after a first-inning argument with home plate umpire Todd Tichenor earned him an early exit to the clubhouse during Chicago's matchup at Yankee Stadium. The White Sox' manager was outraged when first baseman Paul Konerko was called out on strikes, and wasted no time getting into a heated battle with Tichenor.
Replays of the strike-three call showed that the pitch was well below Konerko's knees, but that made no difference in Guillen's fate.
Once he reached the clubhouse, Guillen immediately hopped on his Twitter account to comment about the situation.
"This one going to cost me a lot money," his first Tweet read. "This is patetic [sic]."
Guillen didn't stop there. The manager tweeted another comment moments later, likely taking a dig at Tichenor.
"Today a tough guy show up a yankee stadium," the second tweet read.
The Yankees went on to defeat the White Sox 3-1 in the matchup.
