Bonds hit a fairly typical .303/.438/.609 with 37 homers, 28 steals and 130 walks in 1998, but his performance was lost amid the McGwire-Sosa home run chase. The story that later emerged from reporters Mark Fainaru-Wada and Lance Williams in their book Game of Shadows is that the attention accorded to those two sluggers motivated Bonds to take performance-enhancing drugs to keep up; after that season, he began training with Greg Anderson, a weightlifter and steroid dealer. Amid his intense training regimen, he tore a triceps tendon in his right elbow, costing him seven weeks of the 1999 season, but he still hit 34 homers in just 102 games. He set a career-high with 49 homers in 2000—second in the league, one short of Sosa's total—and hit .306/.440/.688, good for WAR (third in the league). Playing their first year in Pacific Bell Park, the Giants won the NL West but fell to the Mets in the Division Series. Bonds also lost out on the MVP award to Kent, who hit .334/.424/.596 with 34 homers and WAR but drove in 125 runs, 19 more than his teammate.
In January 2004, Major League Baseball announced a new drug policy which originally included random, offseason testing and 10-day suspensions for first-time offenders, 30-days for second-time offenders, 60-days for third-time offenders, and one year for fourth-time offenders, all without pay, in an effort to curtail performance-enhancing drug use (PED) in professional baseball. This policy strengthened baseball's pre-existing ban on controlled substances , including steroids, which has been in effect since 1991.  The policy was to be reviewed in 2008, but under pressure from the . Congress , on November 15, 2005, players and owners agreed to tougher penalties; a 50-game suspension for a first offense, a 100-game suspension for a second, and a lifetime ban for a third.
No player in the Hall of Fame has admitted to using steroids. But Mr. Rodriguez and Mr. Bagwell were suspected of it during their careers. Rodriguez, a 14-time All Star catcher, was accused of using PEDs by his teammate on the Texas Rangers, Jose Canseco. Mr. Canseco alleged in a 2005 tell-all book, “Juiced” that he injected the catcher with steroids. When Rodriguez was asked in 2009 if he was on the list of players who allegedly tested positive for steroids during baseball’s 2003 survey it instituted that year, he told the Associated Press, “ Only God knows .”
