NEW YORK – Commissioner Bud Selig asked Jason Giambi to speak with former Sen. George Mitchell of Maine within two weeks, which would make the New York Yankees star the first active player known to cooperate with baseball’s steroids investigator.

Selig deferred a decision on whether to discipline Giambi for recent remarks that many interpreted as an admission of steroids use.

“Any admission regarding the use of illegal performance-enhancing substances, no matter how casual, must be taken seriously,” Selig said. “It is in the best interests of baseball for everyone, including players, to cooperate with Senator Mitchell in his investigation.”

Mitchell, a former Senate Majority Leader, has been investigating steroids since he was hired by Selig in March 2006.
