A previously elusive figure in the Biogenesis performance-enhancing drug scandal has spoken out, saying clinic founder Anthony Bosch visited Alex Rodriguez during last year's American League Championship Series after the New York Yankees slugger sought his help amid a 1-for-9 slump.

The Yankees, when contacted by the New York Daily News, said they had no knowledge of Bosch's presence in Detroit at the ALCS. The Tigers swept the Yankees before going on to lose the World Series to the San Francisco Giants.

ESPN's "Outside the Lines" reported earlier in June that Rodriguez could be one of about 20 players MLB may seek to suspend in connection to Biogenesis and, along with Milwaukee Brewers slugger Ryan Braun, could face a 100-game suspension.

Porter Fischer, who has been described in some clinic documents as a marketing director before having an apparent falling-out with Bosch last year, also told the Miami New Times in a story published on the weekly newspaper's website that Major League Baseball paid him $5,000 for clinic records he turned over to the league in its investigation of the clinic's South Florida reach.

Sources have told ESPN's "Outside the Lines" that Fischer left Biogenesis of America in September. Fischer, two sources said, had invested $20,000 in the company but grew disenchanted with Bosch and demanded his money back. The sources said Bosch eventually paid Fischer the $20,000 but refused to pay an additional $4,000 that Fischer said he was owed.

Bosch informed Rodriguez that Fischer was threatening to expose the operation, and Rodriguez gave Bosch at least $4,000 "to make it go away," the sources said.

MLB investigators have found some of Fischer's information as it relates to Rodriguez credible, sources previously told ESPN.

According to the New Times report, Fischer also said he took Biogenesis documents and in January supplied them to the New Times -- which later broke the Biogenesis story -- to spite Bosch over the money he felt he was owed. Fischer said an MLB investigator offered him $10,000 more if he handed over the remaining documents he says he had taken from the clinic.
