Josh Zipin of Manhattan rushed over from Arthur Ashe Stadium to the Grandstand court of the Billie Jean King National Tennis Center on Thursday hoping to catch the final set of John Isner’s singles match. Zipin, 34, said he had never seen Isner play live, and wanted to see what his “insane” serve looked like in person. “Somebody behind me was asking if Isner served to you 100 times, how many times could you return it in the court and the person sitting behind me said one,” Zipin said. “I think that’s probably being generous.”For 16 years, Isner, the 38-year-old American star, has wowed fans around the world with his signature game, which combined a booming serve, powerful groundstrokes, and quick hands at the net with volleys and overheads.
