Moreno (adductor) hit in a batting cage Tuesday, Alex Weiner of ArizonaSports.com reports.
Tuesday marks the first time Moreno has swung a bat since he landed on the injured list Aug. 6 with a left adductor strain. The 24-year-old backstop still isn't expected to return to the big-league lineup until well into September, but seeing him resume activity is certainly a positive sign.
