Major League Baseball commissioner Bud Selig says that his science adviser is examining the human growth hormone blood test available through the World Anti-Doping Agency. Selig added that he isn't sure when the study will be completed. "As soon as Dr. [Gary] Green [of UCLA] has finished his study on things, believe me, I'm most anxious to move forward," Selig said. "One can debate what HGH does or doesn't do. It needs to be banned."
