Sebastien Bourdais pulled away following a late caution to win Sunday at the Milwaukee Mile, his second IndyCar victory of the season.

Bourdais was dominating before the caution flag came out on Lap 222 after Justin Wilson's car stalled. He held on when racing resumed for an 18-lap sprint to the finish, turning aside a brief challenge from second-place Helio Castroneves to win by 2.2 seconds.

It was Bourdais' 34th career victory, and first at an oval since winning at Milwaukee in 2006.

Castroneves had a remarkable run after starting last in the 24-car field. Graham Rahal was third.

Bourdais won what overall was a relatively clean race — but far less stressful for drivers than the frantic, five-wide scrums two weeks ago at the superspeedway in Fontana.
