Trucks: Keselowski denies Wallace at Bristol

Brad Keselowski held off Darrell Wallace Jr. for his first NASCAR Camping World Truck Series victory as he won the rain-delayed UNOH 200 at Bristol Motor Speedway.

Keselowski came into the race having not won in 61 career Truck Series starts, but that all changed on Thursday morning. The 2012 Sprint Cup Series champion is now one of 25 drivers with a win in all three NASCAR national series.

"It means a lot as a driver and i don't want to understate that," Keselowski said. "My family has been a part of this series since its inception, and i feel like I have, too."

Keselowski joins his dad Bob to become the only father-son duo to each score a victory in Camping World Truck Series history.

Kyle Busch and Keselowski dominated the race, which was originally scheduled for Wednesday night but postponed by rain, as the Sprint Cup stars led a combined all of the 200 laps. Overall, Keselowski led 119 laps and Busch led 81 laps. However, Busch dropped off in the latter quarter of the race, smacked the wall with 24 laps to go and settled for a 24th-place finish.

Ron Hornaday finished in third, followed by Matt Crafton and Johnny Sauter to round out the top five.

Sauter maintains his points lead with an eight-point advantage over his ThorSport Racing teammate Crafton.

The NASCAR Camping World Truck Series will be back in action for the Chevrolet Silverado 250 at Canadian Tire Motorsport Park next Sunday (1:30 p.m. ET, FOX Sports 1)
