The 23-year-old superstar in the making created a media firestorm by qualifying fourth for the Indianapolis 500, but she won't be racing until Sunday. Meanwhile, Mishael Abbott, also 23, will make her Speedway debut today in the Infiniti Pro Series Freedom 100.

Already with two top-10 finishes this season, Abbott is the first woman to compete in the Indy Racing League's developmental program. She qualified Thursday at 183.125 mph and will start 14th among the 18 drivers in today's race.

"We struggled getting the car going the first two [practice] sessions," she said. "But I was flat all the way around and I drove what I got. Now we have to go back and see if we can pick up a little more speed."

Sam Schmidt Motorsports teammates Jaime Camara and Travis Gregg, meanwhile, took the top two spots in qualifying.

Don't I know you?

Some familiar names are in the Freedom 100 Infiniti race today.

Al Unser, the 22-year-old son of Al Unser Jr. and grandson of Al Unser Sr., qualified seventh at 186.258 mph; and Marco Andretti, the 18-year-old son of Michael Andretti and grandson of Mario Andretti, qualified 10th at 185.219.

Cole Carter, whose father Pancho Carter and grandfather Duane Carter combined for 28 starts in the Indy 500, was third-fastest qualifier at 189.191 mph. Rocky Moran Jr., whose father drove in the Indianapolis 500 three times, was awarded the 18th and final starting spot after mechanical problems during practice prevented him from qualifying.

Putting on a show

Kati Castroneves, older sister of two-time Indy winner Helio Castroneves, designed the shirts worn Thursday in the annual Indy 500 charity fashion show.

"This is something I always wanted to do," said Kati, who is her brother's business manager. "I enjoy making new designs with a variety of shirts. . . . I'm so excited that the girls want to wear my clothing."

The annual fashion show is sponsored by Championship Auto Racing Auxiliary.
