Aryna Sabalenka and Jessica Pegula will face off in the tournament's women's singles final this weekend. It will be a rematch of August's final at the Cincinnati Open, which Sabalenka won.

Jessica Pegula is seeded No. 6 and Emma Navarro is seeded No. 13. Both women are New York natives.

Electronic line judging has replaced humans at the U.S. Open. But the voices making calls are real people, recorded with varying levels of urgency to sell the call, depending on how close the shot is.

Carlos Alcaraz and Frances Tiafoe engaged in a high-level, high-energy spectacle of a back-and-forth semifinal — no point over when it seemed to be, no ball out of reach, no angle too audacious.

Frances Tiafoe topped Russia's Andrey Rublev 7-6 (3), 7-6 (0), 6-4 behind the backing of a boisterous partisan crowd in Arthur Ashe Stadium on Wednesday.
