This will be the second name change since the park opened as Pacific Bell Park, thanks to the acquisition of Pacific Telesis Corp. by SBC, followed a few years later by SBC buying AT&T and renaming the resultant company AT&T. I'd like to think this will put an end to the name changes for a while.
During the park's initial phase, some of us joked that they'd named the field for a pioneering Korean baseball player. (I hope y'all can figure that one out, and I hope it isn't considered offensive in these politically correct times.)
Me, I prefer the idea of naming the park for the city's most famous resident, His Imperial Majesty the Emperor of these United States and Protector of Mexico.
