Nationals manager Manny Acta isn't letting rumors of his demise bother him.

"I don't worry about rumors," Acta said Tuesday night. "When your number is up, your number is up. And I don't spend time worrying about that because if I worry and listen and answer to every one of the things that are going to be said about me, I won't have enough time to prepare myself and put this club together."

A number of major league sources claim that Acta will be fired by Washington in the near future.
