Guillorme (groin) could begin a rehab assignment as early as Sunday, Anthony DiComo of MLB.com reports.
Guillorme carried a three-week return timetable after landing on the injured list with a left groin strain Aug. 15, and he seems to be on track in his recovery process since he's closing in on a rehab assignment. Assuming he joins a minor-league affiliate Sunday, it wouldn't be surprising to see him rejoin the Mets sometime the following weekend.
