The Philadelphia Phillies won the National League pennant in 1950, which was a major achievement. Despite the franchise having existed since 1883, it was only the second first-place finish in team history, and it was the first time that the team made it to the World Series since 1915, when the Phillies lost 4-1 to the Red Sox. In 1950, they faced the Yankees.
Of course, they got swept.
On October 14, 1980, the Phillies won their first World Series game since October 8, 1915. A week later, the franchise took home their first World Series championship ever. They proceeded to win the National League Championship in 1983, 1993, 2008, and 2009, winning another championship in 2008.
This run of success appears to have convinced Ruben Amaro that he is a good general manager who makes good decisions about things.
