IndyCar Series president of competition Brian Barnhart has said that he will not be taking any action following the latest pit-lane dispute involving Danica Patrick at Mid-Ohio.

The Andretti Green Racing driver confronted Dreyer & Reinbold's Milka Duno after Saturday's practice session, demanding an explanation for what she saw as bad driving by the Venezuelan. When Duno then took exception to Patrick's manner and presence in her pit stall, things got both heated and ugly - ironic for two women to have graced magazine covers - with expletives being issued from both sides.

The incident was captured on camera by a friend of Duno's, and quickly found its way onto both television and the internet.

"She came to our pit box in a very bad way with bad words," Duno later explained to the Indianapolis Star, "If you come in a nice way, perfect, we can talk. If you come in a bad way, you are going to find my bad side. If somebody pushes me and finds my bad side, they are going to get a problem."

The Venezuelan, who accepts that she is unlikely to be racing Patrick on track to often, said that its the histrionics that come with the Motegi winner that she objects to.

"I don't like the show she likes in every race weekend," Duno said, "She can push the guys because they cannot do anything to her, but she cannot push me. We meet on equal condition [as women], and I know what kind of character I have. I don't like drama and I told her 'go away, you are not welcome'."

When Patrick didn't leave immediately, Duno threw a towel in her direction, prompting Patrick to direct foul language back. Patrick said that she didn't regret her part in the altercation, but admitted on Sunday that it had been her first encounter with her rival.

"I've never spoken to her before," Patrick said, "I didn't know what to expect.

"It's hard to locate people once they get away from their car, but I stayed behind the wall. I just wanted to ask what happened, whether she saw me [on track].

"Unfortunately, things involving me tend to evolve. I'm on the hot seat when I do something and when others do something [that involves me]. It's kind of the line that I walk because I'm popular."
