CHICAGO — Chicago White Sox manager Ozzie Guillen has been suspended for two games for arguing balls and strikes then complaining about his ejection on Twitter during the game.

Major League Baseball announced Friday that Guillen also had been fined an undisclosed amount. It was the first time baseball penalized a player, coach or manager for use of the social networking site during a game.

Guillen was tossed Wednesday night for arguing with plate umpire Todd Tichenor in the first inning of Chicago's game against the New York Yankees. He then went on Twitter to say the ejection was pathetic.

Guillen is scheduled to miss the White Sox' home games Friday and Saturday against the Baltimore Orioles.
