The red version of the "White Sox" jerseys will be worn during select games this year (I want to say Wednesday night games). They were worn by the team in the 60's if I remember right. The other jerseys were worn by the team in between the great wars.
I don't think SCEA hates the Angels; I just don't think they get the rights to change them up like they do from other teams. It's been said on here that some teams give a lot more room for SCEA to work with than others.
