Alex Rodriguez paid for Tony Bosch's attorney and later made a wire transfer for nearly $50,000 that the attorney refused to accept, Bosch's attorneys told ESPN's "Outside the Lines."

According to several sources, the second payment was a mistake, but it turned out to be part of Major League Baseball's evidence that Rodriguez attempted to tamper with the league's Biogenesis investigation.

Bosch was the founder of the now-defunct Biogenesis clinic in Coral Gables, Fla., at the center of the league's ongoing drug scandal.
