NEW YORK—Selena Roberts, author of A-Rod: The Many Lives Of Alex Rodriguez, has made a number of fresh allegations against the Yankee slugger in her new biography, most notably that on December 11, 1997, Rodriguez did not put any type of performance-enhancing substance into his body. "Everyone knows that Alex has taken steroids every day of his adult life, and anyone who says otherwise is being irresponsible or just lying to you," said Yankee manager Joe Girardi, who testified to personally watching the third baseman inject himself with an anabolic substance every day for the past year and a half. "I don't care what some journalist says—anyone who knows Alex knows he has put every conceivable steroid and hormone cocktail into his body every single day since he started high school. And probably before then. That's just the kind of guy he is." When asked directly about Roberts' book, A-Rod finished an injection into his buttocks, swallowed a handful of pills, and categorically denied every allegation.
