Wednesday evening, the 2010 World Series takes center stage in the sporting universe, and to help usher it in, the Giants are calling on some former stars to throw out the ceremonial first pitch.

Willie Mays will deliver the actual pitch. But standing alongside him on the mound will be Willie McCovey, Gaylord Perry, Juan Marichal, Orlando Cepeda, and Monte Irvin.

Hall of Famer Mays, of course, is one of the greatest players in baseball history, and played with the Giants from 1951 into 1972, moving with them from New York to San Francisco.

Hall of Famer McCovey spent 19 years with the Giants, from 1959-1973, and again from 1977-1980.

Hall of Famer Perry was with the Giants from 1962-1971. Hall of Famer Marichal (noticing a trend?) was with the Giants from 1960-1973. For Hall of Famer Cepeda, 1958-1966. And for Hall of Famer Irvin, 1949-1955. Irvin spent a decade in the Negro Leagues before becoming the first black player in Giants history. He also had his number (20) retired by the Giants during the 2010 season.
