I recall Wally Moon and the Moonshots--the left field line was about 250', but the screen was even higher than Fenway's infamous Green Monster.
You are correct sir!! I vividly remember attending a few games (1958-1961), watching Moon hit those "Moon shots" over the short left field fence.
The interesting thing about Wally Moon (#9), was that he was a left handed hitter, which means he had learned to hit the ball to the opposite field with power............over the fence, hence the term "Moon shots".
Anybody can pull the ball and go deep. Moon became very proficient at going the other way. As you can image, after a while, he didn't get too many outside pitches at home. He only tried that when the Dodgers where at home, where as you mentioned, because of the configuration of the Coliseum (oval - not made for baseball - originally constructed for the 1932 Olympics for track and field events), it was impossible for them to extend the left field line any further. Hence the short left field fence of 250 feet, and the very high screen.
Every other national league stadium except for the New York Giant's
Polo Grounds stadium: left field: 277, right field: 257 center: 455 (this is the stadium where Giant outfielder
Willie Mays made his infamous over the shoulder catch in deep center field off of
Vic Wertz (Cleveland Indians) in the 1954 world series). The Polo Grounds closed in 1963, and was demolished in April 1964), had a standard left field fence, so there was no reason for Moon to employ those antics in those parks, where they would be nothing more than a routine fly ball out. Moon was still with the Dodgers (an opening day starter) in 1962 when they moved to their current home, Dodger Stadium where the filed was symmetrical. On opening day, it was 340 down each line, and 410 dead center. Of course those dimensions have change several times over the years.
