This is how I remember it: Gussie Busch was the new owner of the Cards as of '53. It was also the first season of the Baltimore Orioles ( prior to that the St. Louis Browns.) Bill Veeck made that decision when Busch with mucho $$$ bought the Cards. So I think Sportsman's Park became Busch Stadium at the start of that year. It was a very difficult park to hit home runs; In deep left center and right center, I think there were fences at about 420 feet. The right field line was just 310 feet, but a screen out there rose to some 40 or 50 feet. Veeck, by the way, wrote a funny book named "Veeck as in Wreck."
