On Saturday, Juan Manuel Marquez will step into the ring for a third time against Manny Pacquiao. This time around, Marquez—who's moving up in weight for the fight—has a new physique. He has retained the services of Angel Hernandez, the strength and conditioning coach who has been working with Jamaican sprinter Usain Bolt. Hernandez has been an omnipresent figure on 24/7, and Marquez's new bulk has been noted by viewers.
Then, last week, a bombshell came from BALCO founder Victor Conte. Angel Hernandez is the person formerly known as Angel "Memo" Heredia. Heredia, with a BALCO connection of his own, has been training both Marquez and Bolt under an assumed name.
In the US **'s 2008 case against track coach Trevor Graham, stemming from the BALCO scandal, Memo Heredia was labeled "Source A." He didn't get that designation because he came first alphabetically. Heredia was the prosecution's star witness, and he gave up comprehensive documentation showing PED use by stars like Marion Jones, Tim Montgomery, Justin Gatlin and C.J. Hunter. But Heredia wasn't just a random eyewitness; he was caught dead to rights as a steroid dealer and user, and testified to save his own skin.
In 2005 federal investigators confronted Heredia with evidence of money laundering and drug trafficking, and offered him a deal: Tell what you know or we'll go after you. He gave up everyone he worked with in US Track and Field, and despite claims he wasn't offered immunity, he has escaped prosecution himself. Graham was convicted of perjury and banned from the sport for life.
From a New York Times profile during the trial:
Mr. Heredia, a former Mexican national discus champion, is a secretive figure on the track circuit who describes himself as a chemist, scientist and nutritionist. The son of a chemist, Mr. Heredia received an undergraduate degree in kinesiology from Texas A&M in Kingsville, records show.
He said he used family connections to pharmacies and labs in Mexico to help his business. For years, Mr. Heredia said, he helped his clients flout the rules and easily avoided detection. Substances like human growth hormone and the blood booster erythropoietin, or EPO, are still virtually impossible to detect, and "it is still easy to use testosterone" with fast-acting creams, he said.
"You combine all these things - boom! - you get amazing results," Mr. Heredia said.
