The San Fierro Packers are a fictional professional baseball team based in San Fierro making it the second sports franchise in San Fierro after the 69ers, and one of three known baseball teams in San Andreas (the others being the Las Venturas Bandits and the Los Santos Saints, supposedly forming some sort of rivalry). Packers apparel can be purchased at ProLaps.
Their logo makes a resemblance to their real-life counterpart, the San Francisco Giants.
As the team is sponsered by Fierro Fudge, it can be assumed that the name is a reference to fudge packer, a derogatory term for a homosexual.
In Grand Theft Auto: IV, civilians walking in Beechwood City and Dukes Boulevard can be seen wearing Packers gear, and their is one player's name that appears on the back of the shirt. His name is LaVergne.
