I was fortunate enough to be at at Candlestick Park to watch him hit an inside-the-park homer. An a-MAYS-ing player.
His playing weight never exceeded 210 pounds.
He also played a key role in the finest pitched game in history: 7/2/1963, the epic duel between Juan Marichal and Warren Spahn. Willie hit the home run that won it for the Giants in the bottom of the 16th inning, 1-0. Both pitchers pitched complete games.
