Tampa, Fla. ? Bud Selig says Alex Rodriguez has “shamed the game,” though the baseball commissioner indicated no plans to punish the three-time AL MVP.

“I am saddened by the revelations,” Selig said in a statement issued Thursday, four days after Rodriguez admitted he used unspecified drugs from 2001-03 while playing for the Texas Rangers. “What Alex did was wrong, and he will have to live with the damage he has done to his name and reputation.”

Players and owners didn’t agree to a joint drug program until August 2002, and testing with punishment didn’t start until 2004.

“It is important to remember that these recent revelations relate to pre-program activity,” Selig said.

“Under our current drug program, if you are caught using steroids and/or amphetamines, you will be punished. Since 2005, every player who has tested positive for steroids has been suspended for as much as 50 games.”

Rodriguez’s admission came two days after Sports Illustrated reported on its Web site that he was among 104 names on a list of players who tested positive for steroids in 2003, when testing was intended to determine the extent of steroid use in baseball.
