On June 30, 2016 Giants manager Bruce Bochy makes a rare decision, eschewing the use of the designated hitter in a road game against the Athletics to allow pitcher Madison Bumgarner to hit for himself. It turns out to be an inspired move as Bumgarner doubles off Dillon Overton in the 3rd inning, sparking a six-run outburst, as the Giants go on to win, 12 – 6. The last team to have deliberately declined to use the DH were the 1976 White Sox who had P Ken Brett bat for himself a few times.
