Isner beats Anderson in Dallas rematch of Wimbledon marathon

John Isner beat Kevin Anderson to advance to the quarterfinals of his hometown Dallas Open, outlasting the South African in their first meeting since a marathon in the Wimbledon semifinals in 2018.

All three sets went to tiebreakers, with Isner holding on, 7-6 (1), 6-7 (7), 7-6 (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.

The third-seeded Isner, who lives about a mile from the SMU tennis facility where the inaugural Dallas event is being held, is seeking his 17th ATP Tour title and is now 9-4 all-time against Anderson.
