Andy Murray targets more success

US Open winner Andy Murray has vowed to end the year on a high after enjoying his best campaign on the tennis court.

The 25-year-old, who won the US Open earlier this month, will attempt to defend his Japan Open title with an opening-round match against Gael Monfils.

"Obviously I have good memories of Tokyo from last year. It's nice to come back. I'd also like to play well at the Tour Finals in London. I didn't have the chance to do that last year," Murray told ESPN.

"It was a very disappointing way to end the year. I want to make sure I'm 100% fit for that tournament and finish the year well there."

Murray is currently ranked at number three in the world.
