The unique midweek feature at Las Vegas Motor Speedway's Bullring was billed as "Wild Wednesday," and the night certainly was that for Dustin Ash in the Super Late Models feature.
The 19-year-old Las Vegan started the 40-lap feature fourth and was running second to Justin Johnson, who led by around 10 car lengths midway through the race. A late surge gave Ash his fifth victory of the season to extend his season points lead.
"I kept running him down, and I knew (Johnson) was catching lapped traffic," said Ash, who will start attending the College of Southern Nevada this year.
Ash's spotters -- father Ken Ash and car chief Aaron Jiminez -- told him to "just race the track and I'd reel him in," he said.
Ash's winning margin over Johnson, who is second in the season points standings, was six-tenths of a second.
Tom Lovelady finished third, Taylor Barton was fourth and Jeff Connors took fifth.
Johnson finished first in the eight-car dash, which put him on the outside of the fourth row in the feature race's inverted starting order.
He moved to second after seven laps, took the lead from Jimmy Parker Jr. five laps later and quickly pulled away to a big lead.
The victory was Ash's second in four days. He won the Silver State Legends Cars championship on the speedway's road course Sunday.
In the 100-lap ASA Speed Trucks feature, Andy Allen of Garden Grove, Calif., led from start to finish, but his victory didn't lack drama.
Las Vegan Steve "Bear" Rzesnowiecky, 15, moved into second place behind Allen after 80 laps. Rzesnowiecky made contact with him with five laps to go after another incident had prompted a caution.
Rzesnowiecky would have remained in second for the restart, but after leaving the track for repairs, he started last among those on the lead lap and finished eighth.
Allen held off two-time NASCAR Busch Series champion Randy LaJoie for the victory.
In other races, Rzesnowiecky won the Legends Cars feature by finishing ahead of Jeremiah Wagner, and Jerod Carpenter won the Thunder Roadster feature.
