Alex de Minaur outmanoeuvred in US Open defeat to Daniil Medvedev

• Australian lets slip one-set lead in 2-6, 6-4, 6-1, 6-2 defeat
• Former champion Medvedev books place in quarter-finals

As Alex de Minaur assessed the various strengths of Daniil Medvedev prior to their US Open fourth round clash, he described the Russian as a grandmaster of chess. In the infancy of a match resplendent for the quality of shotmaking, the Australian seemed a move ahead of the former champion, who was ailing in the heat on Louis Armstrong Stadium.

But the setting of the sun on a stifling day in New York revived Medvedev as the former champion at Flushing Meadows switched the match on its head from midway through the second set, before going on to win 2-6, 6-4, 6-1, 6-1 and book a place in the quarter-finals.
