No. 3 seed Carlos Alcaraz beat Federico Coria of Argentina 6-2, 6-1, 7-5 to reach the third round of the US Open.
Alcaraz earned his 46th win of the season, tying Stefanos Tsitsipas for the ATP Tour lead. Tsitsipas was eliminated in the first round of the US Open.
Coria ended Alcaraz's first professional tournament by eliminating him in the second round in Rio de Janeiro in 2020. Since then, the 19-year-old from Spain has rapidly climbed the world rankings while winning four titles this year.
No. 9 Andrey Rublev, No. 11 Jannik Sinner and No. 15 Marin Cilic, the 2014 US Open champion, advanced, but No. 25 Borna Coric was upset by American Jenson Brooksby 6-4, 7-6 (10), 6-1.
Brooksby reached the fourth round at Flushing Meadows as a 20-year-old last year, winning a set from Novak Djokovic. He will play Alcaraz next.
"I'm going to bring in my best," Alcaraz said. "It's going to be a good, competitive battle out there."
