Berkman's homer was listed as 338' I believe--which would have been enough to carry it out of Busch, with LF listed as 330'.
LF is listed at 330 at Busch, but thats right at the foul pole. It gets further as you get away from the pole. I really doubt that would have carried at Busch, but such are opinions.
The crawford boxes can be misleading. Yes, they are shallow (but not as shallow as Yankee's RF), but they are elevated.
It's still an easier shot than LF in Busch, no question at all about that. The distance cited (330')is what it takes to get over the wall, just the same as the Crawford boxes, what it takes to get the ball into them. That would be akin to saying that the 330' at Busch is the base of the wall, which it isn't. A home run at the LF foul pole in Busch has to be longer than 330' to clear the wall. Everyone knows its easier to hit one in the Crawford boxes than to clear LF in Busch.
