On May 17, 1967, Tim McCarver led the bottom of the ninth off with a pinch hit walk off home run that led the Cardinals to a 3-2 victory over the Philadelphia Phillies at Busch. McCarver was simply getting a day off while John Romano got the call to catch Steve Carlton who turned in a solid performance on the mound by allowing just one run over six and two thirds. However, the Phillies starter Chris Short turned in a solid performance of his own by retiring the first 15 batters he faced through six, before walking Orlando Cepeda to lead off the seventh. Cepeda came around to score after the next batter, Mike Shannon belted a triple, that made it look like the Cardinals were in business. The jubilation of tying the ballgame did not last long, as Philadelphia took the lead right back in the top of the eighth on an RBI by shortstop Bobby Wine. Orlando Cepeda came back with a clutch hit in the bottom of the frame that scored Curt Flood, and tied the ballgame, which set the table for the pinch hit heroics by McCarver in the ninth.
McCarver enjoyed one of the best seasons of his career in 1967, by hitting .295 and knocking in a career high 69 runs. Defensively his efforts led the Cardinals to victory on a regular basis, and because of that he finished second in MVP voting behind his teammate Orlando Cepeda.
