Yogi Berra was a baseball black swan because before he began his career there had never been an everyday catcher who was a consistent middle of the order power hitter. Before Berra, the best catchers in baseball had either not hit much, or had hit well with little power, like Mickey Cochrane. Three possible exceptions to this were Bill Dickey, Gabby Hartnett and Ernie Lombardi but none of them hit with Berra’s power while remaining in the lineup consistently.
