Pederson, who is out of the lineup Tuesday against the Red Sox, has a small fracture in his left hand, Jeff Wilson of AllDLLS.com reports.
The veteran slugger suffered the injury on a hit-by-pitch Saturday against the Diamondbacks, but he's hoping the swelling will subside soon and allow him to play again this season. Pederson is likely to be sidelined at least the next few days as he continues to be evaluated.
