INDIANAPOLIS - NASCAR fined Kasey Kahne's crew chief $10,000 and put him on probation Tuesday for his role in a fight in Tony Stewart's pit at Chicagoland Speedway.

Tommy Baldwin was fined $5,000 for violating a rule prohibiting fights in another team's pit area and $5,000 for not controlling crew members. He also was placed on probation until Dec. 31.

The fight in Stewart's pit happened after the driver spun out race leader Kahne on a restart Sunday in the Tropicana 400.
