Baseball Commissioner Fay Vincent Friday upheld Roger Clemens' five-game suspension and $10,000 fine imposed on the Boston ace by American League President Bobby Brown for his actions in last year's playoffs.

The suspension was to begin with the Red Sox' Friday night game at Kansas City.Vincent said expert testimony by a lip reader backed Clemens' version of his verbal exchange with umpire Terry Cooney, but the commissioner ruled Clemens' physical contact with umpire Jim Evans and threats to Cooney provided just cause for the punishment.

Clemenswas ejected by Cooney, who claimed Clemens used excessive profanity in arguing balls and strikes.

Clemens has posted a 4-0 record this season and has not allowed a run in his last 30 innings. He has an 0.28 earned-run average, has struck out 34 batters and walked five. He next is scheduled to pitch Sunday in Kansas City against the Royals.
