It is a familiar stage for the world No2, who went up against American opposition in last year’s final as well, when she was beaten by Coco Gauff.
Sabalenka now gets another attempt to win a first US Open title and third Grand Slam overall, having already extended her superb record in tennis’ biggest events.
The 26-year-old has reached at least the quarter-finals in the last eight Grand Slams she has played in, including when she won the Australian Open in 2023 and 2024.

Victory over Emma Navarro saw Sabalenka comfortably through to this final, where she takes on Pegula, who had never previously made it beyond the quarter-finals at a Slam.
The sixth seed has enjoyed a career-best fortnight, with her title credentials strengthened by a straight-sets win over world No1 Iga Swiatek in the quarter-finals.
Sabalenka and Pegula met just a few weeks ago in the final in Cincinnati, when the Belarusian came out on top.
