Two-time defending champ John Isner advanced to the quarterfinal round of the Hall of Fame Tennis Championships by beating Adrian Mannarino of France 6-0, 7-6 (7) on Wednesday.
The 6-foot-9 Isner served 13 aces in the match that lasted just 59 minutes 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.
The No. 2 seeded Isner needed only 15 minutes to win the opening set, and served four aces in the second-set tiebreak. He closed it out when Mannarino hit a forehand wide off a 131 mph serve.
It was Isner's 12th consecutive win at Newport.
