Former world number one, Andy Murray, has said that he expects to be back to his physical best by January 2020.
The time line would be exactly 12 months after he had the hip resurfacing surgery, which he underwent in a bid to save his career.
Murray, 32, made his long-awaited singles return at the Cincinnati Masters on Monday, which was his first singles match since his Australian Open exit in January.
Although Murray played doubles and mixed doubles at Wimbledon, he announced on Monday, that he would not play singles at this month’s US Open, as he attempts to get back to full fitness that would allow him to play five-set matches at Grand Slams.
“I think nine to 12 months after the operation is when I would expect to be getting close to the best that I can be physically. And speed-wise, I should be fully recovered by 12 months,” Murray told BBC Sport.
“Speeds have improved, but they are quite linear speeds, and repeatable tests, whereas on a match court, you are changing direction and having to react to balls and anticipate,” Murray added.
“The way to get that back is by playing matches. You can hit as many speed targets as you like, but once you get out on court, it’s very different.”
The three-time Grand Slam winner said over the weekend, that he would be playing at the inaugural Zhuhai Championships, which will be held two weeks after the US Open next month.
