Top-seeded Novak Djokovic stayed perfect for 2020 and advanced to the fourth round of the U.S. Open with a straight-sets win.
He beat Germany's Jan-Lennard Struff 6-3, 6-3, 6-1 in an hour and 43 minutes, holding serve throughout. Struff managed only four break points and couldn't convert.
Djokovic has won his last 29 matches and is 26-0 this season, making him a prohibitive favorite to get his fourth U.S. Open title — he won it in 2011, 2015 and 2018. He'll play 20th-seeded Pablo Carreno Busta.
Alexander Zverev, top seed of the bett1HULKS Championship, has booked his spot in the semi-finals of the ATP 250 tournament in Cologne. The World No. 7 from Germany fought past Frenchman Adrian Mannarino 6-4, 6-7(5), 6-4 inside the Lanxess Arena on Friday evening.
Zverev, winner of last week’s bett1HULKS Indoors, struck 16 aces on the slow hard court and won 83 per cent of his first-service points to prevail after two hours and 40 minutes.
