DETROIT - Australian Will Power held off American Graham Rahal by 0.3308 of a second to capture the first of this week's two IndyCar races. Power started only 16th in the field of 22 but passed countryman Ryan Briscoe for a lead on a lap-60 restart and stayed in front of Rahal over the final 10 laps of the 2.36-mile, 13-turn temporary street circuit. "He made it very difficult and he never gave up," Power said of Rahal. "I was worried but I just kept executing good laps. "What a race. It was a tough race. That was hard work. It's a massive win." Power's 23rd career IndyCar triumph was his second victory of the season and put the Australian hot on the heels of Indianapolis 500 winner Ryan Hunter-Reay in the season points race, giving Power 285 to leave him only three adrift of the American.–AFP
