Moreno (adductor) has begun running at 80 percent and is scheduled to catch a bullpen session Wednesday, MLB.com reports.
Moreno is ramping up toward a potential mid-month return. The catcher has been sidelined since Aug. 5 when he suffered a strained left adductor while running out a single. Arizona is getting by with a combination of Adrian Del Castillo and Jose Herrera behind the dish.
