Milwaukee Braves (1953-65)

Milwaukee went wild over the Braves, who were welcomed as genuine heroes. The Braves finished 92-62 in their first season in Milwaukee, and drew a then-NL record 1.8 million fans. The success of the team was noted by many owners. Not coincidentally, the Philadelphia Athletics, St. Louis Browns, Brooklyn Dodgers and New York Giants would leave their original hometowns in the next five years.

As the 1950s progressed, the reinvigorated Braves became increasingly competitive. Sluggers Eddie Mathews and Hank Aaron drove the offense (they would hit a combined 1,226 home runs as Braves, with 850 of those coming while the franchise was in Milwaukee), while Spahn, Lew Burdette and Bob Buhl anchored the rotation.

In 1957, the Braves celebrated their first pennant in nine years spearheaded by Aaron's MVP season, as he led the National League in home runs and RBI. Perhaps the most memorable of his 44 round-trippers that season came on September 23, a two-run walk-off home run that gave the Braves a 4-2 victory over the St. Louis Cardinals and clinched the league championship. The team then went on to its first World Series win in over 40 years, defeating the New York Yankees of Berra, Mantle, and Ford in seven games. Burdette, the Series MVP, threw three complete game victories, giving up only two earned runs.
