Andy Murray beats world no 13 Matteo Berrettini in Beijing
Murray beat the US Open semi-finalist 7-6 7-6 to reach the second round of the China Open.
Andy Murray has claimed his biggest scalp since a second hip operation by beating world number 13 Matteo Berrettini.
Murray won a brace of tie-breaks to move into the second round of the China Open, where he'll meet fellow British player Cameron Norrie on Wednesday.
The 32-year-old underwent hip resurfacing surgery just nine months ago and feared his career was over.
But after a couple of wins on the second-tier Challenger tour and reaching the second round of another tournament in China last week, he has now beaten the US Open semi-finalist Berrettini.
Murray told eurosport.co.uk: "It was a good one to get through. It was obviously pretty tight at the end of both sets. ]
"I think first set I probably served a little bit better at the end, and then the second set there was just a few sort of cat and mouse points at the end, which thankfully I came out on top of one or two more than him, but it was a very tight match and I thought I played pretty well.
"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."
On Thursday, Murray was knocked out of the Zhuhai Championships at the last-16 stage after a three-set tussle with Australia's Alex De Minaur after seeing off Tennys Sandgren in the opening round.
Last month, Murray committed to playing for four weeks in a row as this week's tournament in Beijing is sandwiched in between his outings in Zhuhai and his wild card appointment at the Shanghai Masters before he returns to Europe to compete in the European Open in Antwerp.
