In Google, how do I add a phrase to use in the search but make it optional? (see example below)? - search pitchers of female viginas

Example: Suppose you want to find baseball pitchers deaf. And believe that I am especially interested in the Yankees. How do I search for "baseball pitcher deaf" and add "Yankee" as an option. I want to give priority to the fight with the Yankees, but there are other successes, even if they do not contain "Yankees".
