Both great pitchers. My Dad, brother and I were at Candlestick in 1962 (or 63, I cannot remember) a night game though,,, when Milwaukee Braves Warren Spahn and Juan Marichal locked horns for 16 innings, before Willie Mays hit a solo home run to give the Giants a 1-0 win. That game Ill never forget. We got blankets out of the station wagon and layed on the concrete to nap around the 15th inning.
Juan Marichal took ZERO shit off anyone. You may remember the time he was batting, and Koufax was pitching. Johnny Roseboro was the Dodgers catcher. Roseboro kept zinging the ball close to Marichals head in the batters box, and finally Marichal had enough of it, and got in his face. Roseboro ( a stout son of a bitch himself) leaned in, and Juan took the bat and bopped him in the melon, cutting him and causing a trip to the hospital for stitches.
Later on, I heard they became good friends, and both apologized. Two players with class. Not like that ass Jack "Assassin" Tatum POS.
Marichal was no virgin though. He had excellent control, and aimed for many a batters head, if he thought they were leaning in over HIS plate a bit too far..
