DAYTONA BEACH, Fla. (Aug. 16) - Tony Stewart's temper put a blemish on his near perfect weekend at Watkins Glen International.

On Tuesday, NASCAR fined Stewart $5,000 and Kyle Busch $10,000 for hitting the car of another driver following the completion of races in Watkins Glen over the weekend. Both drivers were placed on probation until December 31.

Driving the No. 33 Chevrolet Monte Carlo owned by Kevin Harvick in Saturday's Busch Series Zippo 200, Stewart made contact with Brian Vickers' Chevrolet after finishing fourth.

On Sunday, Stewart led a track-record 83 of 92 laps to win the Sirius Satellite Radio at the Glen from the pole for his fifth win in the last seven premier series races. However, at the conclusion of that event, Busch rammed Anthony Lazzaro's Dodge Charger to avenge previous contact.
