Last year: Tony Kanaan recorded his second straight win at The Milwaukee Mile. Helio Castroneves, who started from the pole and led several times, had an almost certain victory snatched away when his rear wing collapsed and he crashed with 25 laps to go.

Fast facts: Danica Patrick and Dan Wheldon had a brief confrontation at the end of last year’s race after bumping wheels on lap 88, sending Patrick sliding into the infield. The two had a brief one-sided discussion in the pits, with Patrick putting her arm around Wheldon as she talked with him and then giving him a half-shove as the Englishman walked away. ... Patrick failed to finish for the first time in four trips to Indy after she was banged on pit road by Ryan Briscoe with 29 laps to go. ... Ryan Hunter-Reay was selected the Indy 500’s rookie of the year. The 27-year-old driver for Rahal Letterman Racing started 20th and finished a season-best sixth.
