I haven't made a stadium in a long time...so I sat down to goof off and here is what I ended up with.
Falstaff Field, an alternate history home of the St. Louis Browns (I saved a version minus the Brownie logo should anyone be interested) financed by St. Louis's own Alvin Griesedieck and built within earshot of downtown St. Louis.
Dimensions:
LF line 320
LF 345
LeftCenter 380
Dead Center 419 (at the niche in the wall under the Falstaff logo, between the trees)
RightCenter 380
RF 345
RF line 325
Fences: 8', 14' at dead center
Edit: Added dimensions...
