LONDON, July 9 (Reuters) - Experienced American John Isner ended the run of Greek teenager Stefanos Tsitsipas to reach the quarter-finals of Wimbledon for the first time at the 10th attempt on Monday.
The 33-year-old won 6-4 7-6(8) 7-6(4) to set up a big-serving last eight clash against Canada’s Milos Raonic who overcame Isner’s compatriot Mackenzie McDonald.
There was little between the players in the first set but 19-year-old Tsitsipas, bidding to become the first Greek player to reach a Grand Slam quarter-final, double-faulted twice when serving to stay in the first set at 4-5.
Despite that lapse he recovered well and pushed Isner all the way in the second set and had a set point in the tiebreak which Isner saved with a powerful first serve.
Isner eventually took the tiebreak 10-8 but in a match dominated by serve he could not shake off his stylish young opponent and saved a break point at 4-4 in the third set.
Another tiebreak was inevitable and again Isner’s greater experience was telling as he sealed victory. (Reporting by Martyn Herman Editing by Peter Graff)
