Jessica Pegula became the second American after Coco Gauff to move into the quarter-finals of the US Open on Tuesday morning (AEST) after the eighth seed beat Czech Republic’s Petra Kvitova 6-3, 6-2.
Pegula, who will face either top seed Iga Swiatek or Jule Niemeier, is the highest-ranked American woman and the only player left in the top 10 in both singles and doubles.
She reeled off the last three games of the opening set, which ended with a double-fault by No. 21 Kvitova, and then the last six games of the fourth-round match after trailing 2-0 in the second set.
In the men’s draw, Russian Andrey Rublev downed British seventh seed Cameron Norrie 6-4, 6-4, 6-4 to move into the quarter-finals of a grand slam for the sixth time in his career.
The ninth-seeded Russian, who has never reached the semis at a major, will face either Rafa Nadal or Frances Tiafoe.
