Write a warm, engaging news report about a Torrey Pines and USC alum making his MLB debut the same day his brother is called up by the Phillies. Focus on the moment he receives the save, his debut details (hitless at bat but notable feat), and the family connection, including the shared milestone with his brother and the broader local San Diegan ties. Use the provided specifics: debuting catcher CJ Stubbs for the Nationals, his San Diego roots, and the six San Diegan catchers this season.
