Gregerson (oblique) resumed throwing off flat ground Sunday, Angel Verdejo of the Houston Chronicle reports.

EDGE Analysis

It's the first step in the recovery progress for Gregerson, who was placed on the 15-day DL on Aug. 2 with the oblique strain. The fact that he's already resuming throwing suggests that Gregerson likely won't be sidelined for much longer than the minimum amount of time, putting a mid-to-late August return well within reach. Once healthy, Gregerson will work in a setup role behind newly-appointed closer Ken Giles.
