Pole-sitter Will Power fended off Juan Pablo Montoya to win Sunday at the Milwaukee Mile, giving a huge boost to Team Penske's chances for the IndyCar season title.
The 33-year-old Australian added to the slim lead he had in the standings over teammate Helio Castroneves. A Penske driver has finished second each of the previous four seasons and five of the last six.
Power raced to his third victory of the season, and his first on an oval. He has said his top priority is to win a title for Penske.
Montoya, another Penske driver, finished second. Tony Kanaan was third.
Power's victory ended Ryan Hunter-Reay's two-year winning streak at the Mile. Hunter-Reay won the Indianapolis 500, but his championship hopes took a hit after exiting following 168 laps with mechanical problems.
