On January 25, 2002, Bell was traded to the San Francisco Giants for Desi Relaford so he could have a chance to play every day. Bell scored the 2002 NLCS winning run for the San Francisco Giants from second on Kenny Lofton's single. Bell was the runner bearing down on home plate in Game 5 of the 2002 World Series when J. T. Snow lifted 3 year old batboy Darren Baker out of harm's way. Near the end of the season, he won the Willie Mac Award for his spirit and leadership – as voted on by his teammates and coaching staff.
