That was the end of Bonds's time in Pittsburgh. Now 28 years old, he signed a six-year, $ million contract with the Giants, setting records for the largest deal ever (surpassing Cal Ripken's $ million) and the highest average annual value (beating Ryne Sandberg's $ million). Mays offered to un-retire No. 24 for him to wear, but Bonds instead opted for the No. 25 that his father wore as a Giant from 1968 through '74. He lived up to his new contract with another MVP-winning season in 1993, hitting .336/.458/.677; he led the league in the latter two categories, as well as homers (46), RBIs (123) and intentional walks (43). San Francisco won 103 games but lost out to the 104-win Braves for the NL West flag thanks to a pair of homers by Dodgers rookie Mike Piazza on the final day of the season.
The next year, Bonds's offensive production reached even higher levels, breaking not only his own personal records but several major league records. In the Giants' first 50 games in 2001, he hit 28 home runs, including 17 in May—a career high.  This early stretch included his 500th home run hit on April 17 against Terry Adams of the Los Angeles Dodgers .   He also hit 39 home runs by the All-star break (a major league record), drew a major league record 177 walks, and had a .515 on-base average, a feat not seen since Mickey Mantle and Ted Williams over forty years earlier. Bonds's slugging percentage was a major league record .863  (411 total bases in 476 at-bats), and, most impressively, he ended the season with a major league record 73 home runs.
