Yankees slugger Gary Sheffield injected testosterone and human growth hormone in January 2002, according to the latest revelations in ''Game of Shadows," a book written by two San Francisco Chronicle reporters.
Excerpts from the book appeared earlier this month in Sports Illustrated, giving graphic detail of Barry Bonds's alleged use of a vast array of performance-enhancing drugs, including steroids and human growth hormone. The book by Mark Fainaru-Wada and Lance Williams is scheduled for release today.
Sheffield, who in 2003 reportedly admitted to a federal grand jury to unknowingly having used a steroid cream, also sought to maintain a relationship with Bonds's trainer Greg Anderson after Bonds and Sheffield had a falling out in 2002, according to the book's authors. Anderson was among four convicted in the BALCO steroid distribution scandal.
