On September 18, 1968, just 24 hours after being no-hit by the Giants hurler Gaylord Perry in San Francisco, Cardinals hurler Ray Washburn no-hit those same Giants in San Francisco. The Birds got their runs on ribbies by Curt Flood and Bobby Tolan in the seventh and eighth innings. Washburn walked five, and struck out eight as he worked his way into the history books. In the ninth he had his hands full with two future Hall of Famers in Willie Mays and Willie McCovey due up in the inning. He started off the frame by retiring second baseman Ron Hunt with a groundout. Mays then hit a hotshot to third where Mike Shannon fielded it, then threw him out at first, before McCovey flew out to Flood in center. The no-no was the fifth in franchise history and the first back-to-back no-hitters in the history of the game. It was also the first no-no for the Cardinals since Lon Warneke accomplished the feat in 1941.
