He didn't catch it....
Mickey Mantle Diving for Catch
(Original Caption) Yankee outfielder Mickey Mantle seemingly walking on air, keeps his mouth open as he leaps for a try at White Sox Ed Robinson's homer into the right field stands in the 7th inning of the September 20th clash at the stadium. Although Mickey made a valiant effort to pull down the ball, it sailed into the stands, giving the White Sox a tally and a lucky fan souvenir. The Yanks took the tilt, 5-4.
