Marte (ankle) began hitting in a batting cage Tuesday, Alex Weiner of ArizonaSports.com reports.
It appears to be the first time Marte has swung a bat since landing on the injured list Aug. 19 with an ankle sprain. Manager Torey Lovullo said Tuesday that the 30-year-old infielder is no longer receiving treatment, though it remains unclear how far away he is from a return.
