The big question is will he even be worth using?
Still no timetable but here is a somewhat encouraging update:
Clint Barmes (sprained right knee) will run the bases for the first time Tuesday and work on turning the double play and throwing on the run while ranging to his left. He's scheduled to travel with the Rockies to Chicago, where the Rockies play the White Sox this weekend, and after working out there, he could begin a rehabilitation assignment. Barmes, who was injured May 23, said he feels no pain but has some sensitivity in his knee when making a cross-over move and taking left turns running the bases.
