The Oakland Athletics have blocked the minor league Oakland B's plan to play at the Coliseum for a night in June.

Major League Baseball owners unanimously approved the A's relocation to Las Vegas in November, and the team plans to move into a new stadium on the Las Vegas Strip in 2028. 

The A's have exclusive rights to play professional baseball at the Coliseum and declined to grant consent for the B's based on their license agreement with the Coliseum Authority.

The B's, an expansion club in the independent Pioneer League, were set to begin ticket sales this week for a game June 29 against the Colorado Owlz in what they hoped would be "a celebration of Oakland's baseball legacy and the Coliseum" and "a joyful farewell and celebration."
