Alexander Zverev claims first US Open after four-set battle with Ben Shelton

• No 1 seed wins 6-3, 7-6 (2), 5-7, 6-2

• American's hopes dashed in tense final

For a passing moment at the end of a rugged third set, hope sprung anew for Ben Shelton. He had been outserved and outplayed for nearly three hours, but at 6-5 in the third set, one game from defeat, the American finally broke through. He burst into the return game finally pounding his forehand freely and he willed himself into an unexpected fourth set.

After he had finished pumping his fist, cupping his ear to the crowd and admirably trying to initiate a drastic momentum shift, the next sequence was most revealing. Shelton opened the fourth set with a shaky game, immediately losing his serve at the start of the set. He worked hard until the end, but he was beaten by Zverev, the top seed, who closed out a 6-3, 7-6 (2), 5-7, 6-2 victory to lift his second grand slam title of the year.
