Andy Murray battles past Alexander Zverev to reach Qatar Open last eight

Andy Murray achieved a remarkable result by knocking the fourth seed Alexander Zverev out of the Qatar Open, forcing his way into the quarter-finals in Doha.

The 35-year-old Scot produced a performance of customary grit to edge past Zverev 7-6 (5), 2-6, 7-5 in a gruelling contest lasting more than three hours. His reward is a last-eight match against French qualifier Alexandre Müller on Thursday.

Speaking on court, Murray said: “Obviously I would like to win the matches quicker, but Alex is a top player, he’s a great competitor. He always fights right to the end – it’s one of his biggest strengths – so even once I got that tight first set, he kept going for it, and in the third set I was really hanging on.

“He was creating more of the chances and was the better player for large parts of that. But I managed to stay strong, kept fighting and got the break at the end and closed it out well.”

Murray won the first set on a tiebreak after both players surrendered service repeatedly. The German had served for the set at 5-4, but Murray rallied to level and take it in the breaker.

Zverev’s response was swift as he raced to a 3-0 lead in the second and although the Scot made good use of the new balls to register in the next game, he ultimately went down 6-2 after another break. Murray kept his opponent at bay to win the fourth game of the third set from 30-40 down and level at 2-2, and he scrapped his way to 5-5.

He produced a stunning drop shot and then caused Zverev to hit long to earn the chance to serve for the match, and having earlier been two points away from defeat, made no mistake to seal his passage.

Asked about the imminent meeting with Müller, Murray said: “He’s obviously had a good week this week. Coming through
