Apparently #20 is a marsupial too.

A MLB team in Mexico City would need 100 foot walls at that elevation.

If you think the ball can carry in Denver... just wait until MLB puts a team in Mexico City. It sits at an elevation of 7,382 feet with a minimum elevation of 7,200 feet. Denver’s elevation is 5,130 to 5,690 feet. Good luck with the the pitching staff there.
