FORT WORTH, Texas — Greg Biffle regained the lead when he charged under Jimmie Johnson with 30 laps left Saturday night, then pulled away to end his 49-race winless streak while giving owner Jack Roush another NASCAR Sprint Cup victory in Texas.
"We knew it was a matter of time before we were going to win one of these things. We've been running so good," Biffle said. "Catching the 48 at the end, it was all I had to be able to get to him. It seemed like when we got to him, it was too easy."
Johnson led 156 of the 334 laps while going for owner Rick Hendrick's 200th career victory. But he never recovered, even scraping hard into the wall trying to catch up after Biffle drove under him in Turn 3 and completed the pass before the start-finish line.
"I was surprised I didn't have to deal with him anymore," Biffle said. "I though he was going to be right there."
Biffle, the season points leader, went on to win the fastest Cup race at the 1½-mile, high-banked Texas track. His average speed of 160.577 mph put his Ford 3.2 seconds ahead of the Chevrolet driven by Johnson.
The winning pass came in Turn 3, when Biffle drove his No. 16 under the No. 48 and then swept back in front for the lead before they got back to the start-finish line.
"I just dug deep. I knew I had to do it and kept trying and trying and trying," Biffle said. "I knew the team would forgive me if I wrecked it trying to beat him so I just gave it all I had."
It was Roush's ninth win in 23 Cup races at Texas, and completed a Lone Star State weekend sweep. Ricky Stenhouse Jr. won the Nationwide race on Friday night for Roush's fourth Texas victory in a row and ninth overall in the second-tier series.
"I don't know if this is my last sweep," Roush said. "But I'm going to remember this one for a long time."
Biffle got his 17th career victory. It was his first since an October 2010 race in Kansas, where the series goes next week.
After starting third, Biffle was among the lead pack the entire race, leading 90 laps on a fast-paced and windy night.
There were only two cautions for 10 slowed-down laps, both for debris, and the race finished with a record 234 consecutive laps of green-flag racing.
Mark Martin finished third in a Michael Waltrip-owned Toyota, followed by Jeff Gordon and Roush driver Matt Kenseth. Polesitter Martin Truex Jr., another Waltrip car, finished sixth after leading 68 laps.
Biffle got his eighth consecutive top-10 finish at Texas, where he had a victory in 2005 even before that stretch.
For Hendrick Motorsports, it was the second race in a row that Rick Hendrick was close to getting his first victory of the season and 200th in a career that began in 1984.
Johnson, Gordon and teammate Dale Earnhardt Jr. were running in the top three at Martinsville two weeks ago before a late restart in the last race before the Easter weekend break. But Clint Bowyer's aggressive inside move took out Johnson and Gordon, and Earnhardt ended up third.
"It's nice to be running well. It's nice to be in this position," Johnson said. "But I want to get back to our winning ways really soon."
