The Portland Trail Blazers have played in the National Basketball Association (NBA) since the 1970 season. The Trail Blazers have played in three NBA Finals (1977, 1990, 1992) and have won one NBA Championship (1977). Several of the Trail Blazers' former players are in the Basketball Hall of Fame, including Dražen Petrović, Bill Walton, Lenny Wilkens, Clyde Drexler, and Arvydas Sabonis. Furthermore, the team has retired several numbers including Terry Porter (#30), Maurice Lucas (#20), Larry Steele (#15).
Professional baseball was played nearly continuously in Portland from 1901 until 2010, absent only during the 1994 season. The original Portland Beavers were the longest lived team, playing every season from 1901 to 1972, though occasionally under a different name. Various minor league baseball teams played in Portland thereafter, including revived Beavers teams between 1978 and 1993 and again between 2001 and 2010. Since 2010, there has been no professional baseball played within Portland city limits.
