The Drug Enforcement Administration and Major League Baseball are investigating an Alex Rodriguez adviser linked to performance-enhancing drugs, according to the New York Daily News. Anthony Bosch has worked with Rodriguez on training, nutrition and dietary supplements, along with other Latin ballplayers in south Florida. Bosch is the son of Dr. Pedro Bosch, whom MLB investigated in 2009 for his PED ties to Manny Ramirez when he played for the Los Angeles Dodgers. Pedro Bosch gave Ramirez a prescription for the female fertility drugs for which he tested positive. It was reported that Ramirez, as well as several other players, knew Anthony Bosch. The Daily News reported there has been a rise in the use of synthetic testosterone and human growth hormone in MLB. The league is trying to determine if the Bosch family is supplying players with PEDs. Rodriguez, who may miss the 2013 season after having hip surgery, admitted to PED use in 2009.
