Bosch is the owner and operator of a Miami clinic which allegedly supplied PED's to MLB stars including Rodriguez, Gio Gonzalez, Melky Cabrera, and Nelson Cruz.

Those same sources told ESPN's "Outside The Lines" that while other athletes relied on intermediaries to transport the PED's provided by Bosch, Rodriguez' always received personal treatment.

Major League Baseball is currently investigating the clinic as the center of a widespread doping operation in South Florida, where players used testosterone and human growth hormone to enhance their play.

Sources also said said Bosch spoke openly about his relationship with Rodriguez, and that they reviewed documents detailing the drug regimens and schedules Rodriguez received.

A spokesperson for Rodriguez on Friday said "the allegations are not true."
