Newport - Two-time defending champion John Isner advanced to the Hall of Fame Tennis Championships quarter-finals by beating Adrian Mannarino of France 6-0, 7-6 (9/7) on Wednesday.
Isner served 13 aces in his 12th consecutive win on Newport's grass-courts.
It was a Wimbledon rematch for the pair. Isner retired in the third game of the previous match last month after injuring his left knee.
