Will Power gave Roger Penske and Chevrolet what they desperately wanted by winning the first of two races at the Detroit Grand Prix.

“On his home track and in Chevy’s backyard, it’s a perfect day,” Power said Saturday. “If we can do it again tomorrow, it’ll be even better.”

Power finished 0.3308 seconds ahead of Graham Rahal on the bumpy, 13-turn, 2.36-mile street circuit on Belle Isle.

He started a season-worst 16th and took the lead for good with just more than 10 laps to go when he passed Ryan Briscoe.

“There’s no way we thought we would come from 16th to win,” he said. “But this is IndyCar and anything can happen.”

The Australian held off Rahal to join Indianapolis 500 champion Ryan Hunter-Reay as the series’ drivers with two victories through six races. Power pulled within three points of Hunter-Reay, IndyCar’s points leader.

Power, who won IndyCar’s season-opening race, has 23 career victories to break a tie with Emerson Fittipaldi and Tony Bettenhausen and to match Tommy Milton for 18th on the all-time list.

KYLE BUSCH’S 2ND WIN — Kyle Busch raced to his second victory of the weekend in Dover, Del., taking the checkered flag Saturday in the Nationwide Series race to set himself up for a tripleheader sweep. “I do it for the pure love of the sport and just wanting to be out there,” Busch said. “I’ll keep doing it as long as we can do it.” Busch followed his dominant win Friday night in the Truck Series with another stellar run in Nationwide. He led 124 of 200 laps for his 66th career victory in NASCAR’s second-tier series. He has 134 wins spread over NASCAR’s three major series, though he has yet to win a Cup championship or marquee races such as the Daytona 500, Brickyard 400, Coca-Cola 600 or All-Star race.
