World number one Jannik Sinner continued his quest for a first US Open title as he set up a semi-final with Jack Draper.

Sinner, who came into the tournament under a cloud following his anti-doping scandal, beat Daniil Medvedev in a curious quarter-final, coming out on top with a 6-2 1-6 6-1 6-4 victory.
