Input (English): passage: The Las Vegas metropolitan area is home to many sports, most of which take place in the unincorporated communities around Las Vegas rather than in the city itself. The Las Vegas Valley has two major league professional teams: the Vegas Golden Knights of the National Hockey League (NHL) who began play in 2017 as the region's first major pro team and the Las Vegas Aces of the WNBA. The Oakland Raiders of the National Football League (NFL) will begin play in Las Vegas as the Las Vegas Raiders by 2020 and become the region's third major professional team. Las Vegas is also home to two minor league sports teams: the Las Vegas 51s of the Triple-A Pacific Coast League (Minor League Baseball) and the Las Vegas Lights FC of the United Soccer League, the league at the second level of the U.S. men's soccer league system. Both teams are currently the only teams to actually play in the city of Las Vegas, playing at the city-owned Cashman Field.
