Doha: 2008 and 2009 champion Andy Murray earned his first win of the 2024 season with a superb performance to beat France's Alexandre Muller on Tuesday.
The three Grand Slam winner Murray ended a six-match losing streak with a 6-1, 7-6 (7-5) victory over the world number 75.
A wild celebration showed what it meant to the 36-year-old, who also raised his arms in relief when reminded that it was his first victory of the year.
"Obviously, the last few months have been tough on the court for me, I've not won many matches and lost a lot of close ones, so I'm delighted to get through," said Murray.
"I'm proud I managed to get through the match, get a win, and hopefully this is the start of a better run."
Murray, ranked 50th, plays 18-year-old Jakub Mensik in the second round.
