Roger Clemens calls the report "dangerous and malicious and reckless." Andy Pettitte insists he never took banned drugs. Miguel Tejada says he is being smeared again by scandal.

Some of baseball's biggest stars responded with denials and denunciations Sunday following a Los Angeles Times report in which former pitcher Jason Grimsley accused five players of using performance-enhancing drugs, according to a federal agent's affidavit. The other players cited were Baltimore teammates Brian Roberts and Jay Gibbons.

Grimsley once played with Clemens and Pettitte on the New York Yankees and is now out of baseball. The reliever has admitted using a variety of banned substances and was suspended for 50 games by Major League Baseball.

Clemens and Pettitte, now teammates on the Houston Astros, denied the allegations Sunday.

"I just think it's incredibly dangerous to sit out there and just throw names out there," Clemens said Sunday before the Astros played in Atlanta on the final day of the regular season. "I haven't seen (the report), nor do I need to see it."

"For the people involved it is very dangerous and malicious and reckless on the part of somebody ... to put something out there with somebody else's writing on it," he added.

Clemens said he has been tested "plenty of times" and passed every test.

Pettitte was "stunned" by the report.

"I played with Grimsley for a couple of years in New York and had a great relationship with him," the pitcher said before the Astros' game.

"I've never used any drugs to enhance my performance in baseball. I don't know what else to say except to say it's embarrassing my name would be out there."

In June, federal agents searched Grimsley's home in Arizona after the pitcher admitted using human growth hormone, steroids and amphetamines. Grimsley later was released by the Arizona Diamondbacks.

In a search warrant affidavit signed by IRS Special Agent Jeff Novitzky, the Times reported, he said Grimsley identified other players who had used drugs. Those names were blacked out when the document was released.

"As for Jason Grimsley's affidavit, we have no information regarding how it was obtained or its accuracy," MLB spokesman Richard Levin said Sunday.

All major league players are tested at least twice a year for banned drugs. There is no test for HGH, but it is banned by the sport. Former Senate Majority Leader George Mitchell was hired by MLB to investigate steroids in baseball.

The Times said an unidentified source with access to the document — minus the cross-outs — allowed the newspaper see it but kept the copy. The Times said a second source who had identified the other players provided additional details about the document.

According to the affidavit, the Times said, Grimsley told investigators Clemens and Pettitte "used athletic performance-enhancing drugs."

Houston teammate Lance Berkman said he would be startled to find either of the two pitchers involved, calling the matter "irresponsible" and "unfortunate."

"You just have to be very, very careful when you make accusations like that," he said. "You better be right about it."

The affidavit also alleged Grimsley told federal agents that Roberts, Gibbons and Tejada, all with the Orioles, "took anabolic steroids."

"What can I do? I spent one morning last year with Grimsley," Tejada said Sunday from Boston. "I mean, I already got thrown under the bus with Palmeiro. No, I don't worry about that."

Rafael Palmeiro was suspended last season for using steroids and suggested the positive test may have been the result of a vitamin B-12 shot Tejada gave him. Tejada insisted he did nothing wrong.

Gibbons has said he has passed every test administered by baseball.

"I'm as shocked as anybody else," he said.

Roberts derided the accusations as "ridiculous."

"We've had steroid testing, and I've taken all the tests," he told The (Baltimore) Sun. "There is no point in getting into verbal wars."

Novitzky also was the lead investigator in the Bay Area Laboratory Co-Operative probe. Two BALCO officials and Barry Bonds' personal trainer, Greg Anderson, served jail time after guilty pleas in that investigation.

Grimsley has complained to friends, the Times said, that federal agents attributed statements to him that he did not make.

Randy Hendricks, who represents Clemens and Pettitte, told The Associated Press he questions the conduct of the federal agents.

"I've grown weary of having to defend (Clemens) from innuendo and conjecture about every six months for the last several years when he's complied with all of the rules and regulations," Hendricks said. "Andy is just surprised and stunned, and has no knowledge of any such activity."

Atlanta Braves star Chipper Jones called Clemens and Pettitte "iconic figures" and is convinced of their innocence.

Giants manager Felipe Alou was asked how he thinks Clemens will be treated compared to Bonds.

"I've got to say, Rockets are hard to catch," he said. "I was shocked to see those names on television this morning. Some big names. I said, 'Here we go again."'
