Top Fuel points leader Shawn Langdon shattered the Pacific Raceways record to top qualifying Saturday in the NHRA Northwest Nationals.

Coming off his season-leading fourth victory of the season last weekend in Sonoma, Langdon powered his dragster to a pass of 3.765 seconds at 320.58 mph to earn his fourth No. 1 qualifier of the season and 10th of his career. David Grubnic ran an identical 3.765 at 317.57 during the second qualifying session, but Langdon stayed in the top spot because of his faster speed.

Langdon will meet Troy Buff in the opening round of eliminations.

"That 3.76 is basically what we were trying to run out of the box," said Langdon, who is seeking his first Top Fuel win in Seattle. "It surprised me a little. I saw all these 3.80s and 3.81s in front of us and thought, 'We're doing pretty good if it runs 3.79.' So, it was definitely moving on that run."

Jack Beckman topped the Funny Car field, and Mike Edwards led Pro Stock qualifying.

Beckman, the defending Funny Car champion, also broke the track time record, powering his Dodge Charger to a 4.049 at 303.64. It is the first No. 1 qualifier of the season and the ninth of his career.

Beckman will meet teammate Johnny Gray in the first round of eliminations. Gray is second in points and has a class-best four wins.

In Pro Stock, points leader Edwards made his final qualifying run count, going 6.526 at 212.29 in his Chevy Camaro, breaking both ends of the track record. It gave Edwards the No. 1 spot for the 12th time this year and 53rd in his career. Edwards will meet Deric Kramer in the first round.
