"There has never been one shred of tangible evidence that he ever used these substances and yet he is being slandered today," said Hardin, who called McNamee a "troubled man."
Former Mets clubhouse attendant Kirk Radomski, who was interviewed by Mitchell's team on four occasions, also provided information as part of his plea agreement in a federal steroids case.
Radomski identified a number of former and current players he said he sold steroid and human growth hormone to. Checks and money orders, mailing receipts or shipments, and statements of other witnesses were used to back up Radomski's allegations. Much of this was found in Radomski's seized telephone records.
Radomski pleaded guilty earlier this year to charges that he dealt steroids to players for a decade. He then retreated to his auto-detailing business on Long Island while cooperating with Mitchell. Radomski worked for the Mets as a batboy and then clubhouse attendant for a decade beginning in 1985. He later used the contacts he made while with the Mets to go into business selling steroids and other drugs to ballplayers.
At Radomski's shop Thursday, an athletic-looking man in a black jacket who identified himself as Radomski said he had no comment. "Talk to my lawyer," he said. "This is private property. Please leave."
"Former commissioner Fay Vincent told me that the problem of performance-enhancing substances may be the most serious challenge that baseball has faced since the 1919 Black Sox scandal," Mitchell said.
Rafael Palmeiro, who tested positive for steroids, was among the former players named. So were Kevin Brown, Benito Santiago, Lenny Dykstra, Chuck Knoblauch, David Justice, Mo Vaughn, Todd Hundley and Fernando Vina.
Vina, who played for five teams and worked as an ESPN baseball analyst in 2007, was mentioned in Mitchell's report as part of interviews with Radomski. According to the report, Radomski met Vina in 1993 while the latter was in the Mets' minor league system. Radomski told Mitchell's investigators that he sold anabolic steroids or HGH to Vina "six to eight times during 2000 to 2005" and the report included three checks from Vina to Radomski reflecting purchases of HGH and steroids.
According to the report, Vina's name, with an address and two telephone numbers, was listed in the address book seized from Radomski's residence by federal agents. Mitchell said Vina did not respond to his invitation for "an opportunity to respond" to the allegations.
"We had no idea, but will talk to him about it," Josh Krulewitz, ESPN vice president of public relations, said of references to Vina in the report. "We aren't going to comment further at this time."
Mike Stanton, Scott Schoeneweis, Ron Villone and Jerry Hairston Jr. were among the other current players identified.
"We identify some of the players who were caught up in this drive to gain a competitive advantage," the report said. "Other investigations will no doubt turn up more names and fill in more details, but that is unlikely to significantly alter the description of baseball's 'steroids era' as set forth in this report."
"The illegal use in baseball of these substances also victimizes the majority of players who don't use them. We heard from many former players who believe it was grossly unfair that the users were gaining an advantage," Mitchell said.
