Yes, it’s true, an entire major-league franchise now has a corporate sponsor. Fortunately, it isn’t part of their uniforms yet. But it is part of their official logo. The familiar A with the Diamonback pattern (which is now red and black) has a long rectangle protruding from the right side, in which the words “presented by Gila River Casinos” appear. It’s on their media guide cover and on each end of each dugout. Classy. Remember Chico’s Bail Bonds, the fictitious team sponsor in the Bad News Bears? This smacks of that. Memo to Frank and Jamie McCourt: PLEASE don’t get any ideas.
