The San Francisco Bay Area, which includes the major cities of San Francisco, Oakland and San Jose, hosts six major league sports franchises, as well as several other professional and college sports teams, and hosts other sports events.
The Bay Area is home to two Major League Baseball teams. The San Francisco Giants play at Oracle Park and have won eight World Series titles (three as the San Francisco Giants (2010, 2012, and 2014) and five as the New York Giants). The Oakland Athletics play at the Oakland Coliseum, and the A's have won nine World Series titles (four as the Oakland Athletics, (1972, 1973, 1974, and 1989) and five as the Philadelphia Athletics).
The 1989 World Series was known as the "Earthquake Series", "Bay Bridge Series", and "Battle of the Bay", as both teams played against each other, and Oakland swept the Giants in a 4-game series. However, the series is probably best known for the 1989 Loma Prieta earthquake which struck on the day of Game 3.
The Golden State Warriors returned to San Francisco beginning with the 2019–20 NBA season when the new Chase Center opened in the Mission Bay district. Originally, the Warriors played in Philadelphia, but relocated to San Francisco in 1962 and then to Oakland in 1971. During their days in Oakland, the Warriors won four NBA Finals (1975, 2015, 2017 and 2018).
San Jose hosts the San Jose Sharks of the National Hockey League and play at the SAP Center at San Jose. The Sharks began play in 1991, playing their first two seasons at the Cow Palace before moving to their current home in 1993. They have been Pacific Division champions six times, as well as having won the Presidents' Trophy for the best regular season record in the league in 2009, and the Clarence S. Campbell Bowl as the Western Conference champions in 2016. Though the Sharks have yet to win a Stanley Cup, they made their first Stanley Cup Finals appearance in 2016.
