Adam Wainwright has informed the Cardinals that he prefers to wait until the completion of the season before negotiating over a contract extension.

Wainwright confirmed that general manager John Mozeliak contacted him in the past two weeks about his contract. He is in the first installment of a two-year, $21 million club option.

"I don't want to do anything to create a distraction for me or the team," Wainwright said. "My feeling is it can wait until after the season plays out."
