Vaughn (hand) began hitting on the field Friday, Adam McCalvy of MLB.com reports.
Vaughn was cleared to begin swinging a bat earlier in the week, and he has now started to hit for the first time since undergoing surgery in late March to address a fractured hamate bone. He's slated to visit a doctor Tuesday, at which point he could be cleared to begin a rehab assignment and remain on track for an early-to-mid-May return.
