Major League Baseball owners voted Thursday to allow the Oakland Athletics to move to Las Vegas, according to sources.

The potential move, which comes after more than two decades of failed efforts to secure a new stadium in the city to replace the aging Oakland Coliseum, needed backing from three-quarters of teams at the quarterly owners meetings. 

Prior to the Montreal Expos moving to Washington in 2005, the last MLB team to relocate was the Washington Senators, who became the Texas Rangers in 1972.

The A's moved to Oakland from Kansas City in 1968 and have won four World Series in their 55 years in the city.
