The Cardinals feel that Ryan Theriot is an upgrade at shortstop over incumbent Brendan Ryan. Ryan is now expendable, according to Derrick Goold of the St. Louis Post-Dispatch: "The Cardinals have let other teams know Ryan is available, and they'll look to trade him during next week's winter meetings in Florida, if not sooner."
Ryan doesn't want to leave, but he doesn't have any say in the matter. He's arbitration eligible for the first time, but his dismal offensive career numbers should keep his salary down. The Fielding Bible's love for his 2010 defense might not provide much ammo for his agents at WMG in an arbitration hearing.
Starting shortstops are hard to come by, but the Pirates, Orioles, and Padres might be the only teams in the market.
