Stewart dominates USAC finale at LVMS.

NASCAR Winston Cup champion Tony Stewart won both the USAC Midget and Sprint car finales at the Bullring at Las Vegas Motor Speedway Saturday night.

In the 40-lap Midget car race, Stewart started fifth and took command on lap 19 from Dave Darland. Stewart took the chequered flag followed by Darland, J.J. Yeley and Ron Gregory. Darland won the USAC National Midget title, while Robby Flock won the USAC Western States Midget championship after a sixth-place finish.

In the 40-lap Sprint car race, Stewart started sixth and took command on lap 20 from Jeff Gardner. Stewart took the chequered flag followed by Gardner, Tracy Hines and Brian McClish. Rick Hendrix won the USAC Western Sprint car championship after a 12th-place finish.

"This car was awesome all night," Stewart said. "I was just riding around behind Gardner and I knew that I was faster, but I didn't want to abuse the tyres.

"I saw lap traffic coming and I knew where we were stronger than he was. The timing worked out right and I caught him at the spot where we were strong."
