Every year here in Pittsburgh, when October 13 rolls around, a group of devoted Pirates’ fans, including me, head down to Oakland, the old Forbes Field site. There, adjacent to the 457-foot sign that once stood in the park’s left center field, we celebrate the most glorious moment in Pittsburgh’s sport’s history, the 1960 Pirates’ thrilling upset over the Mickey Mantle, Yogi Berra, Whitey Ford star-studded New York Yankees.
