The Giants are taking an aggressive approach in ace Madison Bumgarner’s recovery from a fractured pinky finger, Kerry Crowley of the Bay Area News Group relays. Manager Bruce Bochy indicated that Bumgarner may only need one rehab start and could return shortly after May 25, when he’s eligible to come off the 60-day DL. Bumgarner hasn’t pitched yet this year, and his debut will be an especially timely one for a San Francisco team that just lost fellow front-of-the-rotation starter Johnny Cueto for up to two months with an elbow strain.
