Andy Murray back in swing of things after posting first footage of himself hitting a tennis ball since surgery

The Brit is attempting to salvage his career after surgery following his Australian Open defeat to Roberto Bautista Agut in January

Andy Murray has stepped up his comeback from injury following a hip operation after sharing a video of him hitting a tennis ball.

The three-time grand slam winner underwent a hip resurfacing operation in January in a last-ditch attempt to solve a problem that first surfaced in the summer of 2017.

And on Monday night, the 31-year-old shared a short clip on his Instagram Story of him hitting forehands and backhands against a wall, with the caption 'It's a start'.

His mother Judy replied to his post on Twitter too, stating: "Where there's a wall, there's a way..."

Murray had a first operation in January 2018 and returned to action at Queen's Club last summer but played only six tournaments last season and was in pain throughout.

His last appearance came at the Australian Open, losing to Roberto Bautista Agut in a gruelling five-set match in the first round, but has said since his surgery that he would love to be able to play at Wimbledon in July.

Murray stated last month that his rehab was going well, yet remains unclear whether it will be enough to extend his career.

"The rehab is slow but going well," the 31-year-old Briton said.

"I want to continue playing, I said that in Australia. The issue is I don't know whether it's possible."
