The San Francisco Giants are keeping a close watch on Madison Bumgarner, with both human and electronic eyes. As well as having manager Bruce Bochy and pitching coach Curt Young in attendance for sessions in the bullpen, the Giants have been using a Rapsodo pitch-tracking device positioned behind the plate and a high-speed camera behind Bumgarner’s left shoulder.
The Giants left-hander broke a finger when his left hand was hit by a line drive in spring training. He made his return at nearby Triple-A Sacramento on Saturday, and is scheduled to start for the Class A San Jose Giants on Thursday.
