The Cardinals opted to non-tender just one of their four arbitration-eligible players prior to Monday's deadline, according to the St. Louis Post-Dispatch. Reliever John Axford will become a free agent, despite posting a 1.74 ERA for the Cardinals in 13 appearances at the end of last season.
Axford made $5.0 million last season in a contract signed with the Brewers prior to arbitration. He finished the season with a 4.02 ERA in 65 innings in his time with both teams.
