The Cincinnati Reds and Pittsburgh Pirates split a doubleheader marked by a free-for-all which is later credited with inspiring Pittsburgh and turning its season around. The fight starts after a 4th inning beanball when Jack Billingham plunks pitcher Bruce Kison, bringing both teams onto the field. When Sparky Anderson accidentally steps on Ed Kirkpatrick’s foot, the Buc catcher shoves the Reds manager, earning him a punch from the Reds’ Andy Kosco. Pedro Borbon pins Daryl Patterson, pulling his hair out and a piece of flesh.
