“Mike Jacobs, a first baseman in the Colorado Rockies organization who has played over 500 games in the major leagues, including dozens with the Mets, is the first professional baseball player to test positive for human growth hormone, a banned performance-enhancing drug.
Major League Baseball announced Thursday that Jacobs, who was playing for the Class AAA Colorado Springs Sky Sox this season, has been suspended for 50 games for failing the drug test. The Rockies subsequently released him.
Jacobs, 30, is the first professional athlete in the United States to test positive for H.G.H., said a spokesman for the World Anti-Doping Agency…
His blood sample was sent to U.C.L.A.’s Olympic Analytical Laboratory, which is accredited by the World Anti-Doping Agency, and scientists there detected H.G.H. in it. The drug, which is believed to boost lean muscle mass and aid in recovery, is illegal to possess in the United States without a doctor’s prescription.”
