I was a Milwaukee Braves fan as a young guy and Warren Spahn , along with Lew Burdette, were the mainstays on the Braves’ pitching staff. Burdette had his own marathon game against Harvey Haddix of the Pirates, but the game I remember most was a 1962 game at Candlestick Park in San Francisco when 42 year old Warren Spahn battled 25 year old Juan Marichal for 16 innings. The Giants’ manager, Alvin Dark, wanted to take Marichal out of the game but Marichal begged him not to do it ”at least until that 42 year old comes out.”
Spahn gave up a solo homer to Willie Mays in the 16th inning for a 1-0 loss. It is generally regarded as the best pitching performances by two pitchers in the same game in Major League history. I had the pleasure of seeing Spahn pitch at County Stadium in Milwaukee on two occasions.
