Alex Rodriguez admitted under oath to federal agents and prosecutors in January that he used performance-enhancing drugs provided to him by Biogenesis founder Anthony Bosch from 2010 to 2012, according to a Miami Herald report Wednesday.

Rodriguez's testimony, given in exchange for immunity, marks the first time he has acknowledged using steroids in connection with Biogenesis, the now-shuttered South Florida anti-aging clinic. He recently completed a season-long PED suspension and is planning to return to the Yankees to fulfill the final three years of his contract.

Attorney Joe Tacopina accompanied Rodriguez to the January meeting at the Drug Enforcement Administration's office in Weston, Florida, according to the Herald. Tacopina declined to comment about Wednesday's report, citing grand jury secrecy laws.

The Yankees and Major League Baseball also declined to comment.

According to the Herald, which said it reviewed a 15-page DEA report about the meeting, Rodriguez confirmed to the feds that he paid Bosch $12,000 a month for drugs, received pre-filled syringes from Bosch and employed his cousin Yuri Sucart as a steroid runner.

Federal prosecutors from the U.S. attorney's office in Miami declined to comment. They are preparing to go to trial in February to prove that a half-dozen people, including Sucart, were involved with distributing steroids in connection with Biogenesis. A spokeswoman for the DEA's Miami division also declined to comment because she said the investigation into Biogenesis remains ongoing.

The Herald report comes two days after a federal judge in Miami unsealed a court filing that revealed A-Rod paid nearly $1 million to Sucart last year in the wake of a threat to reveal the "duties" that the cousin performed over the years for him.

Assistant U.S. attorney Michael Sullivan said in that court filing that Rodriguez "has a prominent role" in the government's case that Sucart distributed testosterone and human growth hormone, suggesting that Rodriguez could be called to testify against his cousin.

Sullivan wrote: "The government will prove [Sucart] personally arranged meetings between Rodriguez and Bosch, where Bosch injected Rodriguez with PEDs; and that [Sucart] received an ample cut of the payments Rodriguez made to Bosch."

Sucart's trial is scheduled to begin in Miami federal court Feb. 9, a little more than two weeks before Rodriguez is slated to report to spring training in Tampa, Florida. Sucart's court-appointed attorney, Edward O'Donnell, did not return a message seeking comment.

According to the Herald, Rodriguez told the federal agents and prosecutors that Sucart introduced him to Bosch late in the 2010 season because the third baseman was having knee problems and wanted to lose five to 10 pounds.

The Herald also reported that Rodriguez told the feds he paid Bosch for the drugs either through Sucart as a middleman, by personal checks made out to cash or even by requesting petty cash from the Yankees' traveling secretary.

Rodriguez revealed all of this in a meeting that the newspaper said took place Jan. 29, 18 days after an arbitrator ruled in favor of Major League Baseball and reduced Rodriguez's 211-game suspension to 162 games.

Rodriguez had adamantly denied receiving PEDs from Bosch in the weeks leading up to the ruling. He responded to the arbitrator's decision by vowing to "exhaust" all legal remedies to continue fighting. But his tune soon changed.

On Feb. 7, Rodriguez dropped his two federal lawsuits against MLB and another against the Major League Baseball Players Association and decided he would not follow through on a threat to report to spring training even though he was suspended. He has kept a low profile ever since.

The Herald also reported that prosecutors have granted immunity in exchange for their testimony to eight additional players, including Manny Ramirez, Ryan Braun, Melky Cabrera, Nelson Cruz and Francisco Cervelli.
