FOUNTAIN, Colo. -- Scott Wimmer won the NASCAR Busch 250 at Pikes Peak International Raceway in a race Saturday that saw a track record 15 lead changes.

Wimmer led for 70 laps and took the lead for good on the 227th lap by overtaking Jason Keller, who finished 1.045 seconds behind.

"Fortunately, I just got my fender up on his right rear quarter (panel) and he didn't run me into the wall,'' Wimmer said. "He let me stay up there and I was able to get past.''

Wimmer collected $91,920 for his first win of the season. He has won five times in the series.

A track temperature of 139 degrees at the start of the race made for a slick road surface, allowing for the lead changes. Ron Hornaday Jr., who finished seventh, led the most laps with 80.

The racers averaged 108.19 mph, and there were three caution flags for 23 laps.

Bobby Hamilton Jr., who started in the pole position, led for 31 laps but spun out in the 63rd lap when he was tapped in the rear by Mike Bliss.

Hamilton returned to the race and finished 25th.

David Vickers, who started fourth, had his day ended early. On Lap 28, Jeremy Clements spun out in Turn 4, which caused Larry Gunselman to spin. Vickers then hit Gunselman.

The early exit dropped Vickers from third to fifth in the season points race. There were no injuries in either crash.
