Cubs third baseman Mike Olt worked out at first base Wednesday during the team's first day of workouts, MLB.com reports.
Olt, who is hoping to compete for the starting third base job during spring training, could wind up serving as a backup at first base, where the team doesn't anyone behind Anthony Rizzo, if he isn't named a starter. Olt made eight appearances at first base in 16 games played in 2012, his last season of major-league action.
