Still-perfect Novak Djokovic advances at US Open
New York: Top-seeded Novak Djokovic stayed perfect for 2020 and advanced to the fourth round of the US 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 breakpoints 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.
