New York
Top-seeded Novak Djokovic puts his undefeated record in 2020 on the line in a third-round match on Day 5 against No. 28 Jan-Lennard Struff.
It's a rematch: Djokovic beat Struff 6-3, 6-1 last week at the Western & Southern Open, part of the 17-time Grand Slam champion's 25-0 start to the season.
In other men's play Friday, No. 4 seed Stefanos Tsitsipas faces No. 27 Borna Coric, and No. 5 Alexander Zverev faces No. 32 Adrian Mannarino.
In a matchup between players who won 2015 junior titles at Flushing Meadows, No. 19 Taylor Fritz, a 22-year-old American, will play No. 12 Dennis Shapovalov, a 21-year-old Canadian.
Five years ago, Fritz was the boys champ in singles, Shapovalov in doubles.
"Honestly, I don't even think I'm playing that great. I'm figuring it out," Pegula said.
"Maybe before, I would have gotten more easily frustrated or not played as smart. I'm staying tough in the really tough moments."
