Heyman indicates that Theriot's continued presence on the free agent market is likely due to his desire of a deal that guarantees significant playing time. It was reported earlier this offseason that the veteran was seeking a regular role.
However, teams appear to be more interested in Theriot as a reserve player, a role he's filled for the past two seasons. The 33-year-old hasn't logged more than 500 plate appearances since 2010, and at this stage of his career he seems better suited as a bench player and reserve middle infielder.
Theriot may be content waiting out the spring in hopes of an injury opening up a more significant role for his services. Still, he could ultimately find that he'll be forced to sign as a backup if he hopes to continue playing.
Theriot spent the 2012 season with the San Francisco Giants, hitting .270/.316/.321 with 16 doubles over 384 plate appearances. He owns a career batting line of .281/.341/.350 over eight seasons in the majors.
