CONCORD, N.C. — Danica Patrick became a worldwide sensation as a rookie at the Indianapolis 500, challenging for victory and becoming the first woman to lead laps.

But Patrick's shift to stock cars is long under way and her ties to IndyCar were cut even further Monday — she said she won't run in this year's Indy 500.

Her focus is entirely on NASCAR, and on May 27 she'll race in the Coca-Cola 600. She said skipping the Indy 500 was a "business decision."

"I hope to do it in the future, the Indy 500 that is, and maybe it will be a double," she said. "But at this point, it's just going to be the Coke 600."
