In the top of the first, White Sox first baseman Paul Konerko was called out on a strike that Konerko apparently believed was low, ending the top of the first. Konerko protested the call and then Guillen was ejected by home plate umpire Todd Tichenor.
After he was ejected, Guillen came out of the dugout and got into Tichenor's face. Guillen continued yelling at Tichenor as Mark Buehrle threw warmup pitches and Tichenor squatted behind White Sox catcher A.J. Pierzynski.
It was Guillen's first ejection of the season and 26th of his career.For more baseball news, rumors and analysis, follow @cbssportsmlb on Twitter or subscribe to the RSS feed.
