Daniil Medvedev is through to his first Grand Slam semi-final thanks to a win over Stan Wawrinka.
Enough with the upsets, already. To lose two great champions in the space of three days was enough of a blow for the US Open; the thought that they could lose three in four days seemed unthinkable. And yet, with the sort of results that have been coming out of Flushing Meadows of late, who knew what was about to happen.
We need not have worried. With the dust barely settled after the departures of Novak Djokovic and Roger Federer, into the Arthur Ashe Stadium strode Rafa Nadal. Now the nailed on favourite to lift the trophy on Sunday night, he restored calm and order to proceedings by beating Diego Schwartzman 6-4, 7-5, 6-2 in a little under three hours.
