DALLAS – John Isner beat Kevin Anderson to advance to the quarter-finals of his hometown Dallas Open on Wednesday night, beating the South African in their first encounter since a marathon semi-final at Wimbledon in 2018 .

All three sets went to a tiebreaker, with Isner holding on, 7-6(1), 6-7(7), 7-6(5). Anderson is the one who survived the second longest match in Wimbledon’s 134-year history – six hours and 36 minutes – for a place in this final. Anderson then lost to Novak Djokovic.

Third-seeded Isner, who lives about a mile from the SMU tennis facility where Dallas’ inaugural event is taking place, is seeking his 17th ATP Tour title and is now 9-4 against Anderson.

Isner won 89% of his first-serve points and the players combined with 56 aces. The former Georgian player will meet the winner between Vasek Posposil and Jurji Rodionov.

Australian Jordan Thompson beat eighth-seeded Brandon Nakashima 7-5, 7-6(1) to advance to the quarter-finals. Thompson is joined by seventh-seeded Marcos Giron, who rallied to beat qualifier Liam Broady, 3-6, 6-3, 6-1.

Fifth-seeded Adrian Mannarino beat Steve Johnson 6-7(2), 6-2, 7-6(2) for just his second head-to-head win over the American and first since 2014. Mannarino will meet the Japanese Yoshihito Nishioka in the round of 16.

Taylor Fritz, seeded number 19 after reaching the fourth round of the Australian Open, played his opener against fellow American Jack Sock on Wednesday night.
