On July 4,1972 Denny McLain makes his National League debut in the second game of a twinbill with the Cubs, called in the 8th inning because of rain. McLain gets no decision in the 3 – 3 tie, but receives a standing ovation at the end from the crowd of 50,597. Atlanta wins the opener, 5 – 1, as Ron Reed beats Juan Pizarro. Paul Casanova’s first National League homer and Mike Lum’s three-run homer in the 7th account for four runs.
