Highlights from the 99th running of the Indianapolis 500

RACE: 99th Indianapolis 500

DATE: May 24, 2015

WINNER: Juan Pablo Montoya

AVERAGE SPEED: 161.341 mph

WHAT HAPPENED: His career at a crossroads, Montoya returned to open-wheel racing from NASCAR with Penske Racing. He swapped the lead with Scott Dixon and Will Power four times in the final 13 laps, the final move coming with four laps to go as Montoya slipped outside of Power in Turn 1 for the lead. He held off Power for the remaining three laps to win his second Indy 500.

NOTABLE: Three crashes during practice sent cars outfitted with new aerokits airborne, forcing safety to the forefront for IndyCar. Among those hurt in a crash was James Hinchcliffe, who nearly lost his life after his leg was impaled by a piece of equipment. Some changes addressed the issue by race day. An a cappella group sang ''Back Home Again in Indiana'' after the retirement the previous year of Jim Nabors.
