(Reuters) - Novak Djokovic was disqualified in the U.S. Open fourth round on Sunday for striking a line judge with a ball after going 5-6 down in the first set against Spain's Pablo Carreno Busta.
Djokovic's exit means there will be a first-time major champion at Flushing Meadows and fifth seed Alexander Zverev will fancy his chances after firing 18 aces in a 6-2 6-2 6-1 dismantling of Alejandro Davidovich Fokina.
Zverev next faces Croatia's Borna Coric, who reached his maiden Grand Slam quarter-final with a 7-5 6-1 6-3 win over Australian Jordan Thompson.
Denis Shapovalov overcame David Goffin 6-7(0) 6-3 6-4 6-3 to become the first Canadian man to advance to the U.S. Open quarter-finals in the Open era.
In the women's draw, unseeded American Shelby Rogers stunned sixth seed Petra Kvitova 7-6(5) 3-6 7-6(6) and will next meet 2018 champion Naomi Osaka, who breezed past Estonia's Anett Kontaveit 6-3 6-4.
Also heading out the door was 2016 winner Angelique Kerber, who lost 6-1 6-4 to American Jennifer Brady.
Brady, who reached the quarter-finals at Flushing Meadows for the first time, meets Kazakhstan's Yulia Putintseva after she scored a 6-3 2-6 6-4 win over Petra Martic.
