it a second time. Cities that have lost, then regained four-sport status are Boston, Detroit, Chicago, Los Angeles, Minneapolis–St. Paul, and the San Francisco Bay Area. Boston had the Yanks of the NFL at the start of the four-major-sport era in 1946, along with the Red Sox, Celtics, Bruins, and Braves. Four-sport status ended when the Yanks became the New York Bulldogs in 1949, and then resumed with the formation of the Boston Patriots (now the New England Patriots) in 1960. Detroit had a charter franchise of the NBA (then called the Basketball Association of America) in 1946, but the Falcons folded after one season. Detroit rejoined the four-sport club when the Fort Wayne Pistons moved to Detroit in 1957. Chicago had a BAA/NBA team fold in 1950, then attracted an expansion franchise in 1961 only to see it move to Baltimore two years later. Chicago rejoined the four-sport club in 1966 with the expansion Bulls. The San Francisco Bay Area had teams in all four sports from the NHL expansion in 1967 until the Seals left for Cleveland in 1976. It regained four-sport status when the expansion San Jose Sharks joined the NHL in 1991. Oakland alone had a grand slam without help from San Francisco from 1971 (when the Golden State Warriors arrived) to 1976. Minneapolis–St. Paul became a member with the arrival of the Minnesota Timberwolves as an expansion NBA franchise in 1989, only to see the NHL's North Stars depart for Dallas in 1993. The Twin Cities regained their status with the NHL's expansion Minnesota Wild in 2000. Greater Los Angeles became a four-sport city in 1967 and remained so for 28 years. In 1993, it joined New York in having two teams in each of the four major sports (MLB's Dodgers and Angels, NFL's Rams and Raiders, NBA's Lakers and Clippers, and NHL's Kings and Ducks), but lost both of its NFL teams in 1995. The Rams moved back to Los Angeles in 2016, restoring the city to four-sport status. Two years later, the city once again joined New York in having two teams from each of the four leagues with the arrival of the former San Diego Chargers. If the American Basketball Association (1967–1976) were considered a major professional sports league, three more cities would be former four-sport metropolises. Pittsburgh—home to the MLB Pirates, the NFL Steelers and the NHL Penguins—also hosted the ABA's
