The 2004 San Francisco Giants season was the Giants' 122nd year in Major League Baseball, their 47th year in San Francisco since their move from New York following the 1957 season, and their fifth at SBC Park. The team finished in second place in the National League West with a 91–71 record, 2 games behind the Los Angeles Dodgers. Barry Bonds became the oldest player in the history of the National League to win the MVP Award. It would be the last winning season San Francisco would have until 2009. The Giants hit 314 doubles, the most in franchise history.

Offseason and spring training

On November 14, 2003, A. J. Pierzynski was traded by the Minnesota Twins with cash to the San Francisco Giants for Joe Nathan, Francisco Liriano, and Boof Bonser. The Giants finished spring training with a record of 11–19, the worst in the Cactus League. This includes split-squad games but excludes any ties or games against non-Major League opponents.
