Michael Weiner, the head of the Players' Union, and other officials met with Yankees players as part of a tour of spring training camps recently. The issue of blood testing for HGH was among the topics discussed. "Our attitude toward any kind of testing, blood or urine, is really the same, that we have to make sure the science is down and with the commissioner's office we will continue to investigate whether the science behind the blood test for HGH is 100 percent sound," Weiner said. "The test has to be administered in a way that's safe for the players, and obviously drawing blood has complications that don't exist with respect to collecting urine. And the test has to be administered in a way where the players can actually go to work. Drawing blood is harder to do."
