SONOMA - Scott Dixon passed Mike Conway with three laps remaining to win Sunday's IndyCar Grand Prix of Sonoma while Will Power stretched his season points lead despite a risky late move. New Zealand's Dixon, the defending series season points champion, won his 35th IndyCar triumph to match Bobby Unser for fifth on the all-time list. Aussie Power attempted a tight pass on Britain's Justin Wilson in the final turns of the last lap but was penalized one spot to make the move all for nought. "I was going for more," Power said. "It looked like an easier move. Justin looked like he was struggling. But it got three-wide through there." Power stretched his point total to 626 and his lead to 51 points over Brazilian teammate Helio Castroneves entering next Saturday's final race of the season.–AFP
