"As soon as Dr. Green has finished his study on things, believe me, I'm most anxious to move forward," Selig told a group representing The Associated Press Sports Editors. "One can debate what HGH does or doesn't do. It needs to be banned."
Green has yet to make a determination about the validity of the test. While HGH is banned in the Major Leagues, there is currently no approved test for it. The Major League Baseball Players Association has publicly stated that it would support a blood test if its validity was guaranteed. Presently, Major League players undergo urine testing only.
Selig also said he had talked with many athletic trainers to discern the prevalence of HGH in baseball.
"The answer is we really don't know," Selig said. "Most think it's relatively low, but they really don't know."
The Commissioner said that if the test were to be adopted by the league, testing would begin with those players under Minor League contracts.
Selig's comments came in the aftermath of the league's latest suspension for performance-enhancing drugs. Reds pitcher Edinson Volquez was suspended for 50 games earlier this week for a positive test of a banned fertility drug. Volquez's suspension was the first of its kind in the Majors since Dodgers' slugger Manny Ramirez received a 50-game ban last season.
"The only thing that it proves is our program is working," Selig said. "We do a lot of education. We'll do more."
