 When the stadium was configured for baseball, the portable sections would be placed in the western quadrant of the stadium and serve as the third-base half of the infield.In the football configuration, these are placed in the northern quadrant of the stadium (covering what is used as left field in the baseball configuration) to allow for the football field to be laid out east-west.This had the advantage of improving sightlines for both sports while keeping the baseball dimensions roughly symmetrical.
