FORT WORTH, Texas -- While the 49-race winless streak was wearing somewhat on Greg Biffle, there were also enough encouraging signs during the 18-month drought that he would win more races.
"It will take years off your life. I've probably lost several," Biffle said. "What kept me going or what keeps your spirit up is when you run good. We have run good, we just hadn't finished."
Until getting to Texas, where Jack Roush's drivers have always been good.
Biffle held on tight in the fastest Sprint Cup race ever on the 1 1/2 -mile, high-banked track, pulling away after charging below Jimmie Johnson for a winning pass with 30 laps remaining on a windy and fast-paced Saturday night.
The NASCAR Sprint Cup season points leader after five consecutive races now has a victory to go with that lofty status.
"To win like this and put a bunch of ground on the guys behind us certainly makes a statement, I think, for all the people that were wondering if this was kind of a fluke that we were still leading the points this far in," Biffle said.
For Roush, it was his ninth victory in 23 Cup races at Texas, and completed a weekend sweep in the Lone Star State. The team owner won his ninth Nationwide race in Texas, and fourth in a row, when Ricky Stenhouse Jr. went to Victory Lane on Friday night.
After passing Johnson with a strong move deep down in Turn 3 -- "I knew the team would forgive me if I wrecked it trying to beat him," Biffle said -- the No. 16 Ford went on to a 3.2-second victory with an average speed of 160.577 mph.
Biffle's 17th career victory was his first since an October 2010 race in Kansas, where the series goes next week.
A decade after winning the Nationwide Series season championship, which came after a NASCAR trucks championship, maybe this could be the year the 42-year-old Biffle becomes the first driver with a NASCAR series trifecta of titles.
"When I moved from the Truck Series to Nationwide, it was a huge step. It was much, much harder. But this year is my year, so I'm going to keep after it all the way to Homestead."
Power wins for Penske
LONG BEACH, Calif. -- Will Power kept Penske Racing perfect this season by picking his way through the field to win at Long Beach.
Power won for the second consecutive IndyCar race even though a penalty levied against Chevrolet forced him to start 12th in the field. Chevy's decision to change the engine for all 11 of its teams drew penalties of 10 starting spots for each driver.
So Power had to weave his way through traffic all day, then hold off Simon Pagenaud to preserve the win.
The Australian won at Barber two weeks ago by driving from ninth to first. Penske has won all three races this season, as Helio Castroneves won the opener.
Pagenaud finished second for his first career podium.

*Kasey Kahne celebrated NASCAR's return to Rockingham (N.C.) Speedway with a victory in the Truck Series race. Kahne held off Turner Motorsports teammate James Buescher for the win. The truck race was the first NASCAR-sanctioned event at The Rock since 2004.
