Murray claims maiden Masters title

The British number one produced a stunning performance to overcome the Serb 7-6 (7/4) 7-6 (7/5) in a thrilling final in Ohio.

"It's huge because to win these tournaments is tough nowadays," the Scot told Sky Sports after his win in two hours and 23 minutes. "I've played five days in these conditions and had eight or nine matches in the last couple of weeks. But I've put in the physical work and it's paid off."

Murray reached the semi-finals in Toronto last week - beating fellow 21-year-old Djokovic along the way - and has further underlined his upsurge in form with his performances in Cincinnati.

There were some jitters towards the end as he needed six match points to take victory but his title was richly deserved.

"I got very nervous and he was hitting the ball really big but I hung in well," Murray added.

"It was tough for both of us and there were a lot of long rallies. Your legs really burn out there and they were some of the hardest conditions of the year.

"But I stayed calm throughout and didn't waste any energy - especially when I went behind in a couple of matches. In the past maybe I'd have let that get to me but now I'm playing top players on a regular basis and I'm better equipped."

Djokovic, a rival of Murray's from their junior days, paid tribute to his friend.

He said: "Well done to Andy. It is his first Masters Series but I am sure there are going to be a lot more."
