Brooklyn, including players from the Brooklyn Atlantics, Excelsior of Brooklyn, Putnams and Eckford of Brooklyn, and the All Stars of New York (Manhattan), including players from the New York Knickerbockers, Gothams (predecessors of the New York Giants), Eagles and Empire, are commonly believed to the first all-star baseball games. Two historical clubs, the Brooklyn Dodgers and New York Giants, were among the most storied clubs in professional baseball, and were home to such players as Jackie Robinson and Willie Mays. The two teams left for California—the Dodgers for Los Angeles and the Giants for San Francisco—in 1957. The city currently has two Major League Baseball teams, the Mets (who were formed in 1962 to replace the Dodgers and, to a lesser extent, the Giants), and the Yankees. Major League Baseball's headquarters are located in New York City, at 245 Park Avenue in Manhattan. Basketball The first national basketball championship for major colleges, the National Invitation Tournament, was held in New York in 1938, and its semifinal and final rounds remain at Madison Square Garden. The NIT has spawned a major early-season tournament known as the NIT Season Tip-Off; the semifinal and final rounds of that event are also held at the Garden. At Madison Square Garden, New Yorkers can watch the New York Knicks play NBA basketball. Through the 2017 WNBA season, the New York Liberty also played at the Garden, but that team's main home has changed twice since then. First, the team moved to Westchester County Center in White Plains in 2018. Then, after the team's 2019 purchase by the owner of the NBA's Brooklyn Nets, the Liberty have moved to the Nets' home of Barclays Center in Brooklyn in 2020. The Nets began playing in Brooklyn in 2012, the first major professional sports team to play in the historic borough in half a century. Before the merger of the defunct American Basketball Association with the NBA during the 1976–77 season, the New York Nets, who shared the same home arena (Nassau Veterans Memorial Coliseum) on Long Island with the NHL's New York Islanders, were a two-time champion in the ABA and starred the famous Hall of Fame forward Julius Erving. During the first season of the merger (1976–77), the Nets continued to play on Long Island, although Erving's contract had by then been sold to the Philadelphia 76ers. The Nets transferred to New Jersey then next season
