The preparation before the US Open at the Winston-Salem Open has so far been successful for both Paire and the young talent Shapovalov.
The fourth day brought a lot of interesting battles when the seeded players played their second matches. Benoit Paire, who is seeded as no.1 in the tournament, was the first to advance to the quarterfinals. Although he lost the first set with his countryman Humbert and was losing 4-2 in the second, he managed to turn the match and advanced to the quarterfinals.
Denis Shapovalov, who has shown a very good form in tournaments in the US so far, went through his match without any problems. He coped with Kecmanovic in 2 sets 6-2 and 6-3.
Hurkacz, 3rd seeded, played experienced Lopez,
who said that it is not yet time to end his career. But Spaniard gave up the match during the second set this time.
Rublev,
who has defeated Roger Federer in Cincinnati, continues in his good performances. Now he managed to win two tie-breaks with Querrey to secure his place in the quarterfinals.
