The legitimacy of Bonds' homerun record has been under intense scrutiny due to questions about possible steroid use. Bonds' alleged long-time steroid abuse is detailed in a new book, "Game of Shadows," written by two San Francisco Chronicle reporters. When asked about the book, MLB Commissioner Bud Selig, who spoke with XM's Schmidt and Castellano shortly after Bonds, said he was more interested in reviewing the material on which the book is based than he is in the book itself.
