"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 in his statement. "More specifically, he answered questions about T/E ratio and possibilities of tampering with samples."

The T/E ratio is a comparison of the levels of testosterone to epitestosterone.

Braun emphatically denied using PEDs throughout the appeal process last winter and reiterated that sentiment Tuesday in his statement, saying he has "nothing to hide."

David Cornwell, the lead attorney for Braun's defense team last winter, also issued a statement Tuesday, asserting that Bosch's contributions were "negligible."

"In the 15 years that I have represented players facing discipline under the various professional sports leagues' substance abuse and steroid programs, I have relied primarily, if not exclusively, on Dr. David L. Black and his team of scientists at Aegis Sciences Corporation in Nashville, Tenn., as my experts with respect to scientific and other matters relevant to the testing of player specimens," Cornwell's statement said. "I was not familiar with Tony Bosch prior to Ryan Braun's case. Bosch was introduced to me at the earliest stage of Ryan's case.

"I found Bosch's value to be negligible, and I followed my prior practice of relying on Aegis in the preparation of Ryan's winning defense."

Braun's name is not listed next to any specific PEDs, according to Yahoo! Sports. He is on a list that includes Alex Rodriguez, Melky Cabrera, Francisco Cervelli, Danny Valencia and Cesar Carrillo, the website reported.

According to the Yahoo! Sports report, Braun's name also appeared directly above a line that reads, "RB 20-30K." Bosch listed amounts of money owed next to the names of other players, according to the report.

But Braun asserted in his statement the "moneys owed" to Bosch were merely compensation for his consultation during the appeal process.

"There was a dispute over compensation for Bosch's work, which is why my lawyer and I are listed under 'moneys owed' and not on any other list," Braun's statement said. "I have nothing to hide and have never had any other relationship with Bosch.

"I will fully cooperate with any inquiry into this matter."

Chris Lyons, an attorney who also represented Braun during his defense, declined comment when contacted by ESPN's "Outside the Lines."

Lyons also was mentioned multiple times in the Biogenesis record, according to Yahoo! Sports.

Lyons represented another athlete whose name appears in Bosch's records, professional tennis player Wayne Odesnik, well before the Braun case.

Odesnik, 27, of Weston, Fla., pleaded guilty to importation of human growth hormone in Australia in March 2010. Customs officials there found eight vials of HGH and other medical paraphernalia in his luggage when he entered the country that January to play in a lead-up tournament for the Australian Open. Odesnik initially lied to authorities, saying he had a prescription for HGH, but later said he had ordered the banned substance from the Internet, according to Australian court documents first reported by ESPN.com. The source of the HGH was not disclosed in court records, and Odesnik refused to address it in subsequent interviews.

The International Tennis Federation suspended Odesnik for two years, but that sanction was later reduced to one year in exchange for providing unspecified "substantial assistance" as permitted under the World Anti-Doping Agency code, and Odesnik played a full season in 2011. Lyons represented Odesnik in that doping case.

The Miami New Times posted documents that show Odesnik's name in notebooks dated from 2009 through 2011. In an emailed response to the New Times, Odesnik, currently ranked No. 154 on the ATP Tour, denied ever having been a client of Bosch's or purchasing any performance-enhancing drugs from "any person."

ITF anti-doping manager Stuart Miller told ESPN.com that the federation, which oversees testing and sanctioning procedures for the men's and women's tours, is following up on the new information regarding Odesnik.
