Paire won 7-6 (1), 6-7 (2), 6-1 over John Isner
in the third round of Cincinnati on Thursday.
Paire battled into his second-ever Masters 1000 quarterfinal, and first since 2013, as he ousted the American after two hours and 18 minutes of play. The 32-year-old Frenchman has struggled mightily during the pandemic, but he appears to be rounding into better form. Paire will face No. 4 seed Andrey Rublev
in the quarterfinals.
