PHILADELPHIA -- An MRI revealed on Saturday that Kevin Frandsen has a stress fracture in his left fibula. He is day to day and the Phillies say he can play to the tolerance of the pain, but he will likely sit out the remainder of this weekend's series against the Rockies.
Frandsen will be reevaluated before the start of Monday's home series against the Marlins, assistant general manager Scott Proefrock said, adding he thought Frandsen sustained the injury during the recent series in Atlanta.
Frandsen has impressed since coming up from Triple-A Lehigh Valley on July 27, compiling multi-hit games in 12 of his 33 starts at third base. Overall, he's hitting .336 with three doubles, a home run and eight RBIs. His 37 hits in August tied for third-most in the National League.
Coupled with Placido Polanco's season-ending back injury, Frandsen's absence leaves the Phillies thin at third base. Utility infielder Michael Martinez started at third for the second straight day on Saturday. Pete Orr, a September call-up, is another option at the hot corner, if needed.
