American teen Nishesh Basavareddy defeated countryman and No. 8 seed Alex Michelsen 2-6, 6-2, 6-4 on Thursday in the quarterfinals of the ASB Classic in Auckland, New Zealand.

At 19, Basavareddy became the youngest U.S. male to reach a tour-level semifinal on a hard court since Reilly Opelka did so at 18 in Atlanta in 2016. He saved five of seven break points in the 1-hour, 42-minute victory to set up a clash with unseeded Frenchman Gael Monfils.

The other semifinal pits No. 7 seed Nuno Borges of Portugal against Belgian qualifier Zizou Bergs. Borges outlasted 19-year-old Jakub Mensik of the Czech Republic 6-7 (4), 6-2, 7-6 (4) and Bergs rallied for a 1-6, 6-2, 6-3 victory over Spain’s Roberto Carballes Baena.
