Jason Giambi escaped punishment from commissioner Bud Selig on Thursday because of the Yankee slugger's charitable work and cooperation with baseball's steroids investigator. Selig, speaking on the second and final day of an owners meeting, called this an "appropriate decision." Giambi has acknowledged a "personal history regarding steroids." He agreed to speak with former Sen. George Mitchell last month after Selig threatened to discipline him if he refused to cooperate. "He's doing a lot of public-service work, and I think that's terribly important," Selig said. "I think it's more important for us to keep getting the message out. He was, I thought, very frank and candid with Sen. Mitchell, at least that was the senator's conclusion. Given everything, this is an appropriate decision."
