Milwaukee Brewers all-star leftfielder Ryan Braun quickly stepped forward with an explanation Tuesday night after a report linked him to a Miami clinic alleged to have sold performance-enhancing drugs to several baseball players.

Yahoo Sports reported it obtained three documents from the Biogenesis anti-aging clinic that contained Braun's name, and said Major League Baseball would investigate the link to the 2011 National League Most Valuable Player. But, unlike the earlier Miami New Times report that cited several players including New York Yankees third baseman Alex Rodriguez, Yahoo Sports said Braun's name was not listed next to any specific performance-enhancing drugs.

Braun, 29, issued a statement explaining the link to Anthony Bosch, who operated the now-defunct clinic. Braun said his lawyers were doing research to aid the appeal of his positive test for elevated testosterone after the 2011 season, which was overturned by an arbitration panel over chain-of-custody issues.

"During the course of preparing for my successful appeal last year, my attorneys, who were previously familiar with Tony Bosch, used him as a consultant," Braun said. "More specifically, he answered questions about T/E ratio (testosterone to epitestosterone) and possibilities of tampering with samples.

"There was a dispute over compensation for Bosch's work, which is why my lawyer and I are listed under 'money's owed' and not on any other list. I have nothing to hide and have never had any other relationship with Bosch. I will fully cooperate with any inquiry into this matter."

Braun referred to multiple mentions in the Biogenesis logs to Chris Lyons, one of the attorneys on his defense team, as well as the coded "RB 20-30 K" next to his name on one of the documents. That code was interpreted to mean $20,000 to $30,000, though there was no mention to what that sum of money pertained.

News of Braun's supposedly confidential positive test leaked after the 2011 season along with his appeal of a looming 50-game suspension. Arbitrator Shyam Das ruled in his favor after hearing that collector Dino Laurenzi Jr. kept Braun's urine sample in the basement of his home over the weekend after saying he could not find an open FedEx office on a Saturday evening.

MLB issued a news release after that ruling saying it "vehemently" disagreed with Das' judgment. MLB officials later exercised their right to fire Das as the sport's independent arbitrator, and worked with the players union to tighten the collection language in the joint drug agreement to ensure there would be no further chain-of-custody disputes.

When the Miami New Times broke the Biogenesis link to baseball players last week, it listed Rodriguez, Melky Cabrera, Gio Gonzalez, Cesar Carrillo, Yasmani Grandal, Bartolo Colon and Nelson Cruz as players receiving PEDs from Bosch at the clinic. Cabrera, Colon and Grandal were suspended for 50 games by MLB after testing positive for elevated testosterone during the 2012 season.
