Girardi, reporter have heated discussion

BALTIMORE -- The Yankees were upset after Mark Teixeira was called out at first base on a game-ending play on Saturday, but their emotions didn't cool once they got off the field.

Manager Joe Girardi engaged in a brief shouting match with columnist Joel Sherman of the New York Post in the visiting clubhouse at Camden Yards, and the pair were separated by team personnel.

Girardi conducted his postgame press conference with reporters in a noisy hallway outside the clubhouse and was irked at having to answer repeated questions about CC Sabathia's health, saying at one point, "I'm not lying. One time is sufficient."

The spat between Girardi and Sherman continued into the manager's office, where players overheard the exchange before Sherman exited and the door slammed shut behind him.
