Backup C Shawn Riggans is having surgery on his right knee in St. Petersburg today and will be sidelined at least two weeks. Riggans has an infection in the bursa sac; just called up Michel Hernandez is likely to be the primary backup.

The Rays have also changed their pitching rotation, flip-flopping James Shields and Matt Garza in the order. That way, Garza will pitch Friday in New York and Shields will be moved back to Saturday. The idea is to give Shields an extra day's rest, to split up Graza and Edwin Jackson in the rotation and to have Shields available to pitch in the Sept. 23 doubleheader at Baltimore.

The result is that Shields won't pitch against Boston next week at the Trop, and Garza won't face his former Twins teammates.

Also 3B Evan Longoria is talking about taking a full batting practice Friday and said it was "possible" he could be in the lineup that night. He said his previously fractured right wrist felt "great" after taking 30 swings at balls thrown by trainer Ron Porterfield.
