Navone seals the biggest victory

Navone, a 25-year-old Argentine who won his first ATP singles title this year, remained level-headed against one of tennis’ greatest players. Djokovic was emotional during the match, his tears seeming to reflect the physical pain and frustration of a difficult night.Speaking on the occasion, Navone said: “It was very difficult for me because you play with the ‘GOAT’ on this court,” said Navone, who idolized Djokovic growing up. “It’s definitely the best I’ve been on court. This is an amazing court and the biggest stage. It’s amazing, the way we play. I mean, five sets… I’m very happy. I don’t know. What can I say?”After securing the biggest win of his career, Navone added, “It’s unbelievable,” Navone said. “That means a lot. It’s a dream come true.”The result raised fresh questions about whether Djokovic, who also crashed out in the first round in Cincinnati earlier this month, will return to the US Open or any Grand Slam again.
