The outfields in the West aren't that big. Arizona and Colorado have big outfields because normal size outfields would regularly lead to 10-9 games. Dodger Stadium is 375 to the gaps and 400 to center. Petco is like 370 to the left center gap, 396 to center and 387 to right center. AT&T is deep in the right field gap at 421 but shallow to right at 309, only 368 to left center and 396 in center.
