Richmond, VA (My Sportsbook) - Kyle Busch celebrated his 24th birthday in style Saturday night by winning the Crown Royal presents the Russ Friedman 400 at Richmond International Raceway.

Just after a restart, Busch made a daring four-wide pass on the outside to take the second position from Carl Edwards and then moved around Jeff Gordon to grab the lead for good with 49 laps remaining.

"We've had four bad weeks, and we knew we had to get back on track somehow," Busch said. "It's my birthday, and I knew (the fans) were all supporting on May 2nd for my birthday tonight, and we pulled out a win for them."

The victory was Busch's third in the Sprint Cup Series this season and the 15th of his career. He also became the second driver to win a Cup race on his birthday. Cale Yarborough won the spring event at Atlanta the day he turned 43 years old on March 27, 1983.

Busch also scored a weekend sweep at Richmond as he won Friday night's Nationwide Series race. He joined Harry Gant (1991) and Kevin Harvick (2005) as those drivers to win both races on the same weekend at the three-quarter- mile track.

"This car wasn't perfect all night," Busch said. "I knew that when we had practice. I kept on telling (crew chief) Steve (Addington), 'Man, it doesn't feel bad, it's not perfect, but we can't get this much more out of it.' Steve made the right call there on when to pit and when to take four tires versus two tires or no tires. And it really paid off for us there at the end to have that long run like that."

Busch became the youngest driver in series history to win his first 15 races.

Tony Stewart came on strong in the closing laps to finish second.

"We got lucky and got a chance to get tires there with 50 laps to go," Stewart said. "We got that green-flag run at the end that we typically don't get. That helped us. We got a lot less laps on our tires than those guys."

Jeff Burton finished third, despite an incident with Dale Earnhardt Jr. midway through the race. Earnhardt Jr. got loose and bumped Burton, putting him into a spin. Earnhardt Jr. finished one lap down in 27th.

Ryan Newman came in fourth to give Stewart-Haas Racing two of the top-five finishing positions.

Newman bumped Mark Martin from behind after a late-race restart, putting Martin into a spin. Martin Truex Jr. hit Martin after the spin.

"We had the leader strategy, but we just got caught up when I turned (Mark Martin's) car around there on that restart. We lost four spots, and those were the four spots we needed to get back to the front."

Martin recovered nicely for a fifth-place finish.

Sam Hornish Jr. came in sixth, while Jamie McMurray was seventh. Gordon fell behind in the late-stages as he finished eighth.

Casey Mears and Juan Pablo Montoya rounded out the top-10.

Denny Hamlin led the most laps with 148, but lost valuable track position after a lug nut problem on a late-race pit stop. He finished 14th. Hamlin also led the most laps in last year's spring race at Richmond, but a tire problem put him out of contention to win.

Three-time defending series champion Jimmie Johnson had a frustrating night at Richmond. Johnson, who had won three of the last four races here, was first penalized for entering pit road too fast. He then lost the brakes in his car and spun on lap 191.

Johnson was later involved in a crash with David Stremme and Kasey Kahne. He ended up finishing 34 laps behind in 36th-place.

The 400-lap event at Richmond saw a track-tying record of 15 cautions - mostly accident-related - for 79 laps.

Gordon reclaimed the lead in the championship standings with a 10-point advantage over Kurt Busch, who finished 12th. Stewart moved up to third in points (-39), while Johnson dropped to sixth (-151).
