Bumgarner represented the National League at the 2014 Major League Baseball All-Star Game, his second straight All-Star selection. However, Bumgarner was unavailable to pitch on July 15 in the All-Star Game because he pitched two days prior to the event. On July 13, in an 8–4 win over the Arizona Diamondbacks at AT&amp;T Park, Bumgarner and Posey each hit grand slams, marking the first-ever occurrence in MLB history that batterymates each hit grand slams in the same game. Bumgarner also tied the all-time MLB records for grand slams in a career and in a single season by a pitcher with two. Tony Cloninger had been the last pitcher to hit two grand slams in one season, doing so in one game on July 3, 1966.
