After returning this year, Montoya has gradually been getting re-acquainted with his old stomping grounds, and his hard work finally paid off with a victory for Team Penske.
Montoya faced competition from Tony Kanaan, but when the 2013 Indy 500 winner's ambitious fuel strategy left him four laps short the Colombian came home to win unchallenged.
The only flashpoint in a drab race, which featured a record-setting 158 laps without a caution, was an incident between team-mates and championship rivals Will Power and Helio Castroneves. After the restart from the sole caution, caused by a Graham Rahal spin, Power was judged to have made two moves to block Castroneves as the cars reached 200mph. The Brazilian was able to swerve to avoid a huge accident, and Power was handed a drive-through penalty as a result.
Thanks to his punishment, Power lost his points advantage and is now tied with Castroneves at the top of the standings. Frenchman Simon Pagenaud is third, forty-four points adrift, while Montoya's win leaves him fifty-five shy in fourth.
