"I feel more athletic now that I can actually do some swinging," Eaton joked. "Everything is going really well."
On Saturday, Eaton is slated to hit some soft toss and hopes next week to get into some extended spring games where he would only hit and not play in the field.
The D-backs said at the time of the injury that Eaton was expected to be out six to eight weeks.
