Musial became the first player to hit five home runs in a day on May 2, 1954, in a home game against the New York Giants. In the first game, Musial went 4-4 with a walk and 3 home runs, including a game winning three-run home run in the bottom of the eigth off Jim Hearn. The Cardinals won the first game, 10-6.
In the second game, Musial hit another two home runs, both flying out of Sportsman’s Park and landing on Grand Avenue, and both coming off of future Hall of Famer Hoyt Wilhelm. And in Musial’s second at-bat, in the third inning, he flied out to deep center, 420 feet away, which would have meant another homer in many other parks. However, his two homers weren’t enough to overcome a 5-5 day from Giants right fielder Don Mueller, and the Cards lost, 9-7.
At the end of the day, Musial finished 6-8, with five home runs, eight RBI, six runs scored, and two walks.
