Christian Red and Ian Begley of the Daily News have dug deeper into the Angel Presinal story, speaking to a former scout who alleges that Presinal was an expert at helping players beat steroid tests.

Presinal told ESPN on Thursday that he had worked with A-Rod during that three-year time frame — a “loosey-goosey” era, in Rodriguez's own words — but the Daily News reported Friday that as recently as 2007, Presinal was accompanying A-Rod throughout that MVP season with the Yankees, staying in the same hotels, often sharing a room with Sucart. Another source told The News that Presinal was with Rodriguez often last fall in both New York and Miami, where the Yankee slugger has homes, and that Rodriguez often flew Presinal to the U.S. ...

According to a former baseball scout, who worked with players who trained with Presinal in the Dominican, Presinal provided some players with steroids. The former scout declined to be named in this story but says that players refer to Presinal as “The Cleaner,” someone who can rid traces of steroids from the players' urine before a drug test.

“He puts them through a cycle and then they flush the body out,” the former scout said. “If you're afraid of testing positive, this is the guy to go to.” He said players are afraid to discuss Presinal because they depend on his expertise as a trainer. It is also expensive to work with Presinal, according to the former scout, who says the trainer charges as much as $10,000 for an offseason session.
