Rockies closer Huston Street says federal investigators may talk to him about a Canadian doctor being investigated in probes involving HGH and another drug. Street was told by his agents that he "might be interviewed by the U.S. attorney's office regarding the case or by the commissioner's office or both." The right-hander says he visited Dr. Anthony Galea in Toronto in 2007 and 2008 while the right-hander was playing for the Athletics. Galea was arrested in Canada last October on four charges relating to an unapproved substance called Actovegin.
