First positive test for HGHA rugby player is news because it's the first time anyone has been caught by a test for HGH. It's a blood test, which is a sticking point with all the player unions, at least to my knowledge. But it might just eliminate one hurdle for getting HGH testing into place, because it's an actual test that works. The unions can't play that card anymore.
Bud Selig's already talking about plans to implement HGH testing at the minor league level. Should be only a matter of time before the MLBPA will have to cave.
