TORONTO -- Jason Giambi will not be disciplined by Major League Baseball for admitting that he has used performance-enhancing substances, commissioner Bud Selig announced Thursday.
The New York Yankees slugger has cooperated in former Sen. George Mitchell's investigation into steroid use in baseball and met with Mitchell and his team last month to answer questions about his experiences using banned substances. He agreed to speak with Mitchell after Selig threatened to discipline him if he refused to cooperate.
"Jason was frank and candid with Senator Mitchell," Selig said in a statement. "That and his impressive charitable endeavors convinced me it was unnecessary to take further action."
In a letter to Giambi, Selig wrote: "In the days since your interview, your representatives have discussed with my office your commitment to off-field charitable activities. For example, your agent has informed my office that you intend to donate $50,000 to the Partnership of a Drug Free America. You have also committed to make an additional donation of $50,000 in cash or equipment to the Harlem RBI."
In May, Giambi told USA Today that the sport should apologize for use of performance-enhancing drugs and that he was "wrong for doing that stuff."
"I was wrong for doing that stuff," Giambi told the newspaper at that time. "What we should have done a long time ago was stand up -- players, ownership, everybody -- and said: 'We made a mistake.'"
"We should have apologized back then and made sure we had a rule in place and gone forward. ... Steroids and all of that was a part of history. But it was a topic that everybody wanted to avoid. Nobody wanted to talk about it," he said.
Giambi told a grand jury during the BALCO investigation in December 2003 that he used steroids and human growth hormone, the San Francisco Chronicle reported in December 2004. Before the start of spring training in 2005, Giambi made repeated general apologies at a news conference but wouldn't discuss whether he used steroids or admitted to the grand jury in 2003 that he did.
A former American League MVP, Giambi missed more than two months this season with torn tissue in his left foot. He's batting .270 with nine home runs and 26 RBIs in 51 games.
