Juan Pablo Montoya held off Will Power to win the 2015 Indianapolis 500.
A wild finish saw Power, Montoya and Scott Dixon exchange the lead multiple times over the final laps with Montoya prevailing to take the checkered flag.
This was Montoya's second victory in the premier North American open-wheel race and Team Penske's 16th overall. He completed the winning pass with three laps to go when he made a brazen dive to the inside of Power down the Indianapolis Motor Speedway front stretch. Power, a Penske teammate of Montoya's, attempted multiple passes for the lead but the 2000 Indianapolis winner fended him off each time.
Dixon of Chip Ganassi Racing started on the pole and led a race-high 84 laps, but faded to fourth. Teammate Charlie Kimball finished third. Graham Rahal was the top finishing Honda driver in fifth.
There were five lead changes over the final 15 laps following a restart for a multi-car wreck in Turn 4.
"Oh my god, that was awesome!" Montoya said. "I don't even know what to say."
Penske and Ganassi cars dominated Sunday, with the teams often holding the top seven positions throughout the afternoon race. IndyCar's two best teams have now combined to win 10 of the past 16 races, and Roger Penske joins Chip Ganassi as the only two car owners to win the Indianapolis 500 and Daytona 500 in the same year. Joey Logano won NASCAR's Daytona 500 in February.
Montoya had to overcome a Lap 1 incident that saw Simona de Silvestro run into him under caution. The contact damaged Montoya's wing and right rear wheel guard and dropped him to 30th after making repairs.
The runner-up finish was Power's best at Indianapolis. He is the defending IndyCar Series champion and more noted for his ability on road courses than ovals.
"Anywhere else I'd be happy with second, but here it sucks," Power said.
After an eventful month where cars flipping became almost commonplace, no drivers got airborne Sunday. The only incidents that occurred were normal racing accidents, the most notable being Tony Kanaan's single-car crash and a three-driver wreck, which set up the 15-lap sprint to the finish.
But two crewmembers were injured when James Davison spun on pit road. The mishap occurred just halfway as the race was under caution for an accident involving Ed Carpenter and Oriol Servia.
Davison was leaving his pit stall when he clipped Pippa Mann, which sent Davidson spinning into the crewmembers for Tristan Vautier, who were serving Vautier's car. One crewmember was loaded into an ambulance and transported to IU Methodist Hospital with a right ankle injury. A second was taken to the infield medical center with a left foot injury. He was evaluated and released.
Davidson, Mann and Vautier all drive for Dale Coyne Racing.
"Unfortunately I got sent out there at the same time Pippa was coming and we made contact and it sent us into our second team car," Davison said. "Just a very unfortunate situation.
"I'm really hoping he's okay. I think we took his feet away from him rather than ran him over. Hopefully, he'll make a full recovery."
Neither Carpenter nor Servia were injured in the accident that preceded the pit road collision. The collision occurred when Carpenter attempted to pass Seriva into Turn 1, but Seriva came down and chopped Carpenter, sending both into the wall.
Kanaan was a frontrunner and led 34 laps until he lost control and slammed into the Turn 4 SAFER barrier.
Marco Andretti, Helio Castroneves, J.R. Hildebrand, Josef Newgarden and Simon Pagenaud rounded out the top 10.
