Exploiting playing area rules.

Rules of the Major Baseball League (MBL):

Page 5, 1.04:

NOTE:
(a) Any Playing Field constructed by a professional club after June 1,
1958, shall provide a minimum distance of 325 feet from home
base to the nearest fence, stand or other obstruction on the right and
left field foul lines, and a minimum distance of 400 feet to the center field fence.

(b) No existing playing field shall be remodeled after June 1, 1958, in
such manner as to reduce the distance from home base to the foul
poles and to the center field fence below the minimum specified in
paragraph (a) above.

23%.  That's the percent difference between 325 and 400 using 325 as the base.  Playing areas may be the same distance in fair territory in all directions; no MBL team has ever tried it, only Little League.  The percent difference may be less than 23%; it may be more.  For instance the playing area may be 325 down the lines and 500 in center for a percent difference of 54%, more than twice 23%.

Maybe I missed it but there does not seem to be a requirement that there be a fence, stand or other obstruction in fair territory.  I've long thought that a team can gain a competitive advantage by simply doing something different.  If a team played with no fences in fair territory and put three or more center field quality outfielders in the field at the same time it could minimize the damage to its defense while placing a huge burden on opponents whose rosters could not handle the burden.

On the road the team with no outfield fences at home would probably have trouble scoring because it would probably have sacrificed scoring for fielding among its center fielders.

If that team played four across, it would need to adapt in the infield, probably by having the pitcher actually assume some routine responsibilities, like covering third base in the absence of a third baseman.  I'm guessing that opponents don't work on that much in spring training.

Would such a scenario benefit a team overall?  I'm guessing that it would, that it would win more games.  There would not be any outfield seats but fans might pack the stands to see all those triples and inside the park home runs, the two most exciting plays in baseball, which the current style seems to reduce each season, replaced with more walks, more strike outs and over the fence hits followed by a victory lap that has become mundane at best, obscene at worst.

Try it.  If you're Kansas City or Pittsburgh, what have you got to lose?
