Salvatore Anthony Maglie was an American Major League Baseball pitcher and later, a scout and a pitching coach. He played from 1945 to 1958 for the New York Giants, Cleveland Indians, Brooklyn Dodgers, New York Yankees, and St. Louis Cardinals. Maglie was known as "Sal the Barber", because he gave close shaves—that is, pitched inside to hitters. A gentle personality off the field went unnoticed during games, his foreboding physical appearance contributing to his menacing presence on a pitcher's mound. He was the last of 14 players to play for the Giants, Dodgers and Yankees at a time when all three teams were in New York City. During a 10-year major league baseball career, Maglie compiled 119 wins, 862 strikeouts, and a 3.15 earned run average.

The New York Giants were a Major League Baseball team in the National League that began play in the 1883 season as the New York Gothams and became known as the Giants in 1885. They continued as the New York Giants until the team moved to San Francisco, California after the 1957 season, where the team continues its history as the San Francisco Giants. The team moved west at the same time as its longtime rival, the Brooklyn Dodgers, also in the National League, moved to Los Angeles in southern California as the Los Angeles Dodgers, continuing the National League, same-state rivalry.
