Greg Anderson raced to his sixth career victory in the K&N Horsepower Challenge by defeating Shane Gray in the final round at The Strip at Las Vegas Motor Speedway on Saturday.

Anderson powered his Pro Stock Summit Racing Equipment Chevy Camaro to a 6.684-second pass at 205.47 mph to better Gray's 6.699 at 206.26 and claim the $50,000 prize and the opportunity to walk away from the weekend with more than $100,000. With a victory in Sunday's DENSO Spark Plugs NHRA Nationals elimination bracket, Anderson could earn an additional $50,000, including a $25,000 sweep bonus.

"It's been a great start to the season, first of all," Anderson said. "This day is all about fun. All about thanking K&N for all they do for this class, for this sport and a whole big pile of cash at the end of the rainbow and we found our way there.

"It's just a lot of fun. We have a chance to double up tomorrow. It adds more pressure, but more fun for tomorrow. It's going to be a great day tomorrow."

He opened the challenge as the No. 2 seed and outran Drew Skillman and Ken Black Racing teammate Bo Butner to advance to the finals. It was Anderson's sixth victory, second in a row, in the Pro Stock bonus event.

In other racing, Steve Torrence (Top Fuel), Courtney Force (Funny Car) and Jason Line (Pro Stock) secured the No. 1 qualifying positions in their respective categories at the fourth of 24 events on the 2017 NHRA Mello Yello Drag Racing Series schedule.

Torrence held on to the top spot with his 3.720 run at 327.03 in his Capco Contractors dragster from Friday. This was the 14th No. 1 qualifier of his career and first of the season.

"We seem to have a good handle on the conditions here in Las Vegas," Torrence said. "When we come here, we typically run well right out of the trailer. We usually run well on Q1 and then we build on that. And that's huge for going rounds on Sunday, but even just even doing well in qualifying for having a good base and a good platform to tune off."

Eight-time World Champion Tony Schumacher and his U.S. Army dragster are in the No. 2 spot and will face Terry Haddock in the first round of eliminations. Doug Kalitta was third.

Courtney Force set The Strip at Las Vegas Motor Speedway's elapsed time track record in Funny Car with her No. 1 qualifying pass of 3.867 at 327.66 in the Advanced Auto Parts Chevy Camaro on Friday, a time that held up to make her the top qualifier for Sunday.

"This is an awesome run for our team," Force said. "To head down there and run a 3.86 to set the track record, that definitely felt good. It was a great run for us, and we're excited about it.

"It all comes down to tomorrow, though. Our main goal is going rounds tomorrow and heading to the winner's circle in Vegas."

This was the 11th No. 1 qualifier of Force's career, and she will face Gary Densham in the first round of eliminations. Matt Hagan qualified in the second position and will line up against 2015 Funny Car World Champion Del Worsham, while Tim Wilkerson is in the third spot.

Line maintained his No. 1 qualifier status with his 6.647 pass at 206.29 in his Summit Racing Equipment Chevy Camaro from the weekend's first qualifying session on Friday.

"The strategy is to go out there and go as fast as you can every time," Line said. "Obviously try to do the best job you can to get every bit of performance out of the race car. It's not just me. I'm just one small part of it. I'm the guy who can mess it up.

"[Crew chief] Rob [Downing] and the guys do a really good job of getting the race car down the race track. It's a very good hot rod right now."

It was Line's 53rd No. 1 qualifier of his career. Veteran Jeg Coughlin qualified second in his JEGs.com / Elite Performance Chevy Camaro and will race Tom Huggins.

Eliminations for the DENSO Spark Plugs NHRA Nationals will begin at noon Pacific Time on Sunday. Watch the action live on FOX Sports 1 at 3 p.m. PT.
