This file contains "stadium_st02.iff", which will replace your Spring Training Facility 2 stadium, which I assume is the Cactus League park.
Ads and scenery were designed by DaSteelerz in HD.
Grass/dirt have been imported from Picklebrad's work
Lighting/miscellaneous textures were made by me.
To install, simply put this file in your main MLB2K12 directory, replacing the existing stadium_st02.iff file.
As part of a combined effort from all of us at MVPMods, enjoy!
