Australia’s Jordan Thompson has beaten eighth-seeded Brandon Nakashima 7-5 7-6 (7-1) to advance to the quarter-finals of the Dallas Open.

The Sydneysider sent down 13 aces and won 81 per cent of points on his first serve.

Thompson claimed the only break of the match, in the first set, and saved all eight of his in the two hours 14 minute triumph to set up a clash with either Italy’s Andreas Seppi or number four seed Jenson Brooksby.

Top-seeded Taylor Fritz, ranked a career-high No.19 after reaching the fourth round of the Australian Open, enjoyed a 6-1 6-4 win over fellow American Jack Sock.

He’ll face Marcos Giron next after the seventh seed rallied from a set down to beat British qualifier 3-6 6-3 6-1.

John Isner beat Kevin Anderson to advance in his hometown event, outlasting the South African in their first meeting since a marathon in the 2018 Wimbledon semi-finals.

All three sets went to tiebreakers, with Isner holding on, 7-6 (7-1) 6-7 (9-7) 7-6 (7-5). Anderson was the one who survived the second-longest match in Wimbledon’s 134-year history — six hours and 36 minutes — for a spot in that final. Anderson went on to lose to Novak Djokovic.

“It was a good atmosphere for sure and very happy to win that match, especially when I truthfully kind of choked in the second set. Just great to win and I knew it was going to be a coin flip match,” Isner said.

The third-seeded Isner won 89 per cent of his first-serve points, and the players combined for 56 aces. Isner will meet the winner between Vasek Posposil and Jurji Rodionov in the last eight.

Fifth seed Adrian Mannarino beat Steve Johnson 6-7 (7-2) 6-2 7-6 (7-2) for just his second head-to-head win against the American and first since 2014. Italian Mannarino will meet Japan’s Yoshihito Nishioka in the round of 16.
