On Saturday, third-ranked Alexander Zverev was stunned by Felix Auger-Aliassime in the third round of the U.S. Open.

Tommy Paul’s loss means there is just one American, Taylor Fritz, left in the year’s final Grand Slam. He faces Tomas Machac on Sunday.

Stars Carlos Alcaraz (ranked No. 2) and Novak Djokovic (No. 7) are also both in action, facing off with Arthur Rinderknech and Jan-Lennard Struff, respectively.

Three American women also play — No. 4 Jessica Pegula plays Ann Li in an All-American clash while Taylor Townsend takes on Barbora Krejcikova.

Aryna Sabalenka, the top-ranked women’s player, plays Cristina Busca.
