A French open quarter-finalist, Zverev, saved four set points on his serve at 5-3 in the first but could do nothing to stop the 34-year-old Brown from serving out the first set a game later. The world number five, who has never won a title on grass, improved in the second and quickly broke in the second game to race 5-2 clear. Yet Brown continued to mix it up and broke back to level at 6-6 before his opponent, who served 14 double faults, clinched the second set 7-3 in the tiebreak. Brown saved three break points at 3-3 in the third and never looked back, racing to finish it on his first match point. “It’s a big win. The last few years have been a bit up and down with injuries. So I am very happy and especially that it happened in three sets which was mentally very challenging,” said Brown. “I stayed cool, tried to play deep and am happy to have won it.” He will now play the winner of Frenchman Gilles Simon’s match against Canadian seventh seed Felix Auger-Aliassime in the last eight.
