EDGE Analysis

Duda continues to work his way back from a back injury that forced him to the disabled list Aug. 22. While he won't make it back when first eligible, he took a positive step forward in the rehab process Wednesday. It's still a little difficult to place an exact timetable on him, but it should clear up a bit as the rehab progresses further.
