You might be thinking of Jim Bouton.

Jim Bunning was one helluva' pitcher and the most conservative man in the Senate.   As a pitcher he had a Hall of Fame record and indeed is in the Hall but also he is one of the most exclusive group of ballplayers ever......men who threw a perfect game. I think its like less than 20 or so. A perfect game has no runs, hits, errors, or walks. No one was ever on base on the opposing team which was the Mets. Bunning was playing for the Phillies.I was 15 and I really remember it well.

As a Senator, he's an asshole.
