Brad Keselowski won the NASCAR Nationwide Series event at Charlotte Motor Speedway Saturday, leading the final 67 laps to give Penske Racing a winning start on auto racing's biggest weekend. Keselowski raced to his first Nationwide victory of the year. He'll try to double up in Sprint Cup's longest race of the season, the Coca-Cola 600 Sunday. In between comes the Indy 500, a race that owner Roger Penske's cars have won 15 times. Penske driver Ryan Briscoe will start from the pole there Sunday. Penske Racing has “three shots at winning races this weekend,” Keselowski said. “We're one for one.” Don't bet against more Penske wins this weekend. The team's other drivers in Indianapolis, Will Power and Helio Castroneves, start fifth and sixth. Power has won three times already this year, and Castroneves is a three-time Indy winner. Keselowski led the way as Sprint Cup drivers took the top four spots. Denny Hamlin was second, followed by Kyle Busch and Kevin Harvick, last year's Coca-Cola 600 champion. Nationwide points leader Ricky Stenhouse Jr. had driveshaft problems and finished 26th. Danica Patrick started the race in third, yet slid to 13th. She'll also race Sunday after spending her past seven Memorial Day weekends driving in Indianapolis. The wildest day most likely belonged to X-Games standout Travis Pastrana. He spun out in qualifying, then spun twice more during the race. Pastrana apologized to his crew after the last slide, explaining, “I have no idea what's going on.” Pastrana came home 24th, his second-best showing in four Nationwide Series races. Elliott Sadler, second in points, finished fifth and moved 13 points behind Stenhouse in the standings. Patrick took third in morning qualifying and thought she was in good position for a strong finish. But she quickly fell backward on the hot, slippery track. Still, Patrick was running at the end and posted her third top 15-finish in her past four Nationwide events.
