Larkin struggled with a groin injury in 2001, prompting criticism of his play. Broadcaster Joe Nuxhall said on air that Larkin had "lost it". By August, the injury had limited Larkin to 45 games. He underwent season-ending surgery for a hernia that had been diagnosed during an evaluation of the groin injury. During the 2002 season, Larkin played in 145 games but hit for the lowest batting average (.245) since his first full year in the major leagues. Though he did not miss many games, Larkin dealt with injuries to his rib cage, hamstring, shoulder, neck and toe.
