With the formation of the ABA in February 1967 a team was awarded to Oakland, California for $30,000 with singer Pat Boone as primary owner. The team was originally the Oakland Americans but the name was eventually changed to the Oakland Oaks. NBA star Rick Barry signed with the Oaks, as did Steve Jones and Levern Tart. Barry, however, was prevented from playing in the ABA due to a lawsuit brought by his former NBA team, so he spent the season as the Oaks' radio announcer instead of as a player. The Oaks won the very first ABA game in 1967 and the Oaks breezed through the 1969 ABA Playoffs and won the 1969 ABA Championship over the Indiana Pacers. However, the Bank of America was threatening to foreclose on a $1.2 million loan to the team and in August 1969 a group of Washington, D.C. investors led by Earl Foreman bought the team and moved it to Washington for the upcoming season.
The one season (1969–70)
With the move came a new identity for the team as the green and gold clad Washington Caps. Al Bianchi was the team's coach. A federal appeals court ruled in favor of the Caps regarding Rick Barry's contract. Barry openly objected to playing in Washington, DC, and sat out the first 32 games of the season, but the courts eventually forced him to report to the team. Barry and Warren Armstrong both played in the ABA All Star game but injuries limited their playing time for the season. In March 1970 the ABA-NBA merger appeared close at hand under conditions that would have required the Washington Caps to relocate, but a subsequent lawsuit derailed the merger until June 1976. In defiance of all geographic reality, the Caps assumed the Oaks' place in the Western Division despite their move to the Eastern Seaboard. This kept them constantly on the road at faraway venues and the travel and time differential took its toll on their play. Playing at Washington Coliseum their average attendance was 2,992 fans per game. In a case of exceptionally bad timing, the Caps arrived at a time when the surrounding Near Northeast neighborhood was still recovering from the 1968 race riots. Fears that the neighborhood wasn't safe dragged down attendance. Due to the long travel distances involved in divisional play, the Caps played some home games in places like Wichita, Kansas and even Mexico City, Mexico but did not fare well in those supposed home games. However, due to a solid record in their real home games, the Caps finished the season with 44 wins and 40 losses. The Caps' record put them in third place in the Western Division, 7 games behind the Denver Rockets and 1 game behind the Dallas Chaparrals. In the 1970 ABA Playoffs the Caps faced the Denver Rockets in the Western Division semifinals and took the series to seven games before losing 143-119 in the finale in Denver.

Virginia Squires
After the conclusion of the 1969-1970 season the Caps moved south and became the Virginia Squires, a regional franchise based primarily in Norfolk. At the time, merger talks with the NBA were underway, and the owner of the NBA's Baltimore Bullets, Abe Pollin, wanted to move his team to Washington. The other ABA owners persuaded Foreman to move the Caps for the second time in as many seasons. Foreman decided to make the Caps a regional franchise, the Virginia Squires. While the team would be based in Norfolk and play most of their games at the Norfolk Scope and the Old Dominion University Fieldhouse, they also played home games in Hampton at the Hampton Roads Coliseum, in Richmond at the Richmond Coliseum and in Roanoke at the Roanoke Civic Center. However, Roanoke was dropped from the list of "home" cities after only one season. The Squires' colors were red, white, and blue. The Squires would continue to play in every ABA season through 1976. At the conclusion of the 1975-1976 season the Squires, having fallen on hard times, were unable to make a league-mandated financial assessment. The Squires were disbanded after the season but just prior to the ABA-NBA merger in June 1976.
