Jessica Pegula has advanced to the US Open semifinals for the third consecutive year, defeating compatriot Emma Navarro 3-6, 6-4, 6-3 in an all-American quarterfinal at Arthur Ashe Stadium in Flushing Meadows, New York. The victory sets up a highly anticipated rematch with two-time defending champion Aryna Sabalenka, scheduled for Thursday.

The match, delayed by more than an hour due to Frances Tiafoe's marathon victory on the same court, was a grind from the start. Both players struggled to find rhythm in humid conditions, combining for nine breaks of serve and multiple double faults throughout. Navarro, a former world number eight who returned to competition this year after a health-related break and claimed a title in Strasbourg in May, took the opening set before Pegula steadily wrestled back control. "It was really tough, really physical," said the third-seeded Pegula, who is ranked third in the world. "I wasn't serving my best. I was fighting a lot of demons out there." The win was Pegula's 50th of the season, making her the first player on the women's tour to reach that milestone in 2026, and extended her unbeaten record against Navarro to five matches.

Sabalenka, who beat Pegula in the 2024 final and again in last year's semifinal on the way to her second straight title, reached the last four through a dramatic three-set battle of her own against Czech player Linda Noskova, winning 7-6(1), 3-6, 7-6(7). The Belarusian world number one had to come from behind in a tense final-set tiebreak, saving the match with a run of decisive points after Noskova committed a crucial double fault at 3-3. Sabalenka has now won 22 of her last 23 grand slam tiebreaks, a consistency that has earned her the nickname "tiebreak queen."

Beyond the sporting stakes, the match carries implications for the world rankings. Pegula is among three players who could theoretically displace Sabalenka at the top, but only if she goes all the way to the title. However, second-ranked Elena Rybakina can claim the top spot regardless of other results if she beats China's Zheng Qinwen in their own quarterfinal on Wednesday. The semifinal clash is being dubbed the "Battle of the Billionaires" by American media, a reference to both players' backgrounds. For Pegula, who has won two titles this year, the meeting with Sabalenka represents her clearest route yet to a first grand slam title.
