Andy Murray took another step forward in his comeback by beating US Open semi-finalist Matteo Berrettini in the first round of the China Open.

Italian Berrettini is at a career-high ranking of 13 and is on course to qualify for next month's ATP Finals, so Murray's 7-6 (2) 7-6 (7) victory was hugely impressive considering the Scot only won his first ATP Tour match since January last week.

Murray said on eurosport.co.uk: "It was a good one to get through. It was obviously pretty tight at the end of both sets.

Berrettini had two chances to level the contest in the second-set tie-break but Murray saved both with bold net play and took his first match point.

He will take on fellow British player Cameron Norrie in round two on Wednesday, and Murray said: "Hopefully I can have a good run here. That was a good start for me. I think I play again tomorrow so that will be a good test for me.

"It's the first time I will have played high-level back-to-back days, see how I pull up after that one. But it's a bit of progress for me again this week, which is good.

"I feel like the progress has been quite consistent and hopefully that keeps going through to the end of the year."
