World No. 1 Jannik Sinner and former champion Daniil Medvedev set up a US Open quarter-final showdown on Monday as both men look to exploit the hole left by the shock exits of Novak Djokovic and Carlos Alcaraz. 

Australian Open champion Sinner made the last eight for the second time by seeing off US 14th seed Tommy Paul 7-6 (7-3), 7-6 (7-5), 6-1.
