A newspaper report says some of Major League Baseball's top players, including Roger Clemens, Andy Pettitte and Miguel Tejada, are named in a U.S. government affidavit as using performance enhancing drugs.
The Los Angeles Times says, according to an affidavit by Internal Revenue special agent Jeff Novitzky, former relief pitcher Jason Grimsley named Clemens, Pettitte and Tejada, as well as Brian Roberts and Jay Gibbons as using drugs.
The report says Grimsley spoke to authorities in June after he admitted using human growth hormone, steroids and amphetamines. Grimsley, who played for seven teams in a nearly 14-year career, is quoted in the affidavit as telling investigators he obtained drugs from Brian McNamee, who is a personal trainer for Clemens and Pettitte.
The newspaper says Grimsley has complained he did not make some of the statements attributed to him by the federal agents.
A representative for Clemens and Pettitte denies the accusations of drug use. Tejada, Roberts and Gibbons have not commented.
The Times article says the affidavit quotes Grimsley as telling investigators that Houston pitchers Clemens and Pettitte used "athletic performance-enhancing drugs," and Baltimore's Tejada, Roberts and Gibbons "took anabolic steroids."
Following his admission of drug use in June, Major League Baseball suspended Grimsley for 50 games. He was released by the Arizona Diamondbacks at his request before serving the suspension, and has not played since.
Clemens is a future Hall of Fame player, and a seven-time winner of the prestigious Cy Young Award. He is considered one of the greatest pitchers of all time. Pettitte and Tejada are former American League Most Valuable Players.
Major League Baseball has been embroiled in a doping scandal in recent years, with allegations of performance enhancing drug use by current and retired star players.
