Andy Murray’s pair of ironman performances this season are giving the Scot a fresh dose of confidence on court.

The 35-year-old is finally seeing the back of more than half a decade of injury struggles with his hip and other problems.

The Scot started his run at this week’s ATP Doha event with a come-from-behind win over Lorenzo Sonego, which included saving match points.

The performance followed his Australian Open marathon victory over Matteo Berrettini last month and showed that his fitness is where he wants it to be.

“I’ve trained very well since Melbourne, I’ve pushed myself very physically since the end of last season,” he said.

“I’ve seen the benefits of that in Australia in the matches I’ve played. I’m trying to continue on that path as much as I can.”

Murray played for two and a half hours in beating Sonego after taking down former Wimbledon finalist Berrettini after nearly five hours.

“I’ve got a lot more confidence in my body – but I don’t think I’m in the best shape of my career.

“I’m sure that when I was 25 or 26 years old physically I was better than I am now, faster and with better movement, but what I did in Australia gave me confidence over the past four or five years.”
