Bonds doped extensively, book says
SCOTTSDALE, Ariz. -- Barry Bonds' alleged steroid use is the story of spring training again, no matter how hard he and the San Francisco Giants try to avoid it and keep the focus on his chase of the home run record. Bonds used a vast array of performance-enhancing drugs -- including steroids and human growth hormone -- for at least five seasons beginning in 1998, according to a book written by two San Francisco Chronicle reporters.
