Cox (oblique) was able to do some baserunning Sunday, Susan Slusser of the San Francisco Chronicle reports.
Cox has been on the injured list since July 8 due to a left oblique strain, but his ability to run the bases suggests that a rehab assignment could soon be on the horizon. The rookie outfielder had produced a .269/.269/.500 batting line with one home run, four stolen bases, three RBI and five runs over 29 plate appearances with the Giants prior to landing on the shelf.
