San Francisco's 2011 All-Star team contingent consisted of starting pitchers Matt Cain, Tim Lincecum and Ryan Vogelsong; closer Brian Wilson; and infielder Pablo Sandoval. It was the most Giants on a National League All-Star squad since 1966, when future Hall of Famers Willie Mays, Willie McCovey, Juan Marichal and Gaylord Perry were selected along with catcher Tom Haller and third baseman Jim Ray Hart. San Francisco manager Bruce Bochy became the first winning All-Star skipper in a Giants uniform since Alvin Dark in 1963.
