Marte (ankle) is expected to begin running on a pool treadmill soon, MLB.com reports.
It's unclear when the pool work will begin, or if Marte can return after a minimum stay on the IL. Marte, who injured his left ankle Aug. 10, had a couple of failed attempts to get back on the field, but the Diamondbacks finally added him to the 10-day injured list Aug. 19. The team decided Marte simply needed rest.
