On April 30, 1961, Willie Mays, the legendary center fielder for the San Francisco Giants, hit four home runs in a single game against the Milwaukee Braves at County Stadium in Milwaukee, Wisconsin. This incredible feat marked the second time Mays had accomplished this in his illustrious career, having previously hit four home runs in a game on April 30, 1954, against the St. Louis Cardinals.

In the 1961 game, Mays hit a solo home run in the first inning off Braves starter Lew Burdette. He followed up with another solo shot in the third inning, and then a three-run blast in the sixth, both off reliever Seth Morehead. Mays capped off his incredible performance with a towering solo home run in the eighth inning off Don McMahon, becoming only the seventh player in MLB history to hit four homers in a single game.

The Giants won the game 14-4, with Mays driving in eight runs and scoring four times. His final stat line for the day was 4-for-5 with four home runs, eight RBIs, and four runs scored. This performance further cemented Mays' status as one of the greatest players in baseball history and showcased his incredible power, speed, and overall skill set.

Interestingly, all four of Mays' home runs that day were hit to different parts of the ballpark – left field, center field, right field, and left-center field – displaying his ability to hit for power to all fields. The historic game also helped propel the Giants to the National League pennant that season, although they would eventually lose to the New York Yankees in the World Series.

Willie Mays' four-homer game on April 30, 1961, remains one of the most iconic individual performances in sports history and a testament to his enduring legacy as one of baseball's all-time greats.
