British number one doubles star Jamie Murray is backing the new-look pairing of Wimbledon's Ross Hutchins and Norfolk's Jamie Auckland to break into the world's top 100 this season, writes Craig Chisnall.

Hutchins, 22, is ranked 108th in the world, but Murray is convinced his partnership with fellow Brit Auckland could catapult the pairing into the world-class bracket.

Murray, whose brother Andy is the British number one, turned his back on singles and that decision proved successful when the young Scot clinched the mixed doubles' title at Wimbledon earlier this year alongside Jelena Jankovic.

With Tim Henman and Greg Rusedski having both retired, John Lloyd's British Davis Cup team will rely heavily on the Murray brothers during next year's World Group tie against Argentina.

However, Murray is backing Hutchins and Auckland, who play at this week's St Petersburg Open in Russia, to motor up the world rankings in the doubles in the coming months and provide true international-class support for the Scottish pairing.

"The guys like Auckland and Hutchins have got to grasp this chance," said Murray.

"The only way they will do that is by working hard on the practice courts and producing the results that will see people sit up and take notice.

"It has been great to see Auckland and Ross working their way up the doubles rankings and long may that continue - they look like a formidable pairing.

"Ross took a similar decision to me to focus on the doubles and he has had some encouraging results this year.

"He has an opportunity to really progress and make his mark in 2008.

"The decision to move to doubles worked for me and I have not regretted it - how can I when you look at where I have played?

"I play at the highest level of tennis week in, week out and it has helped my game get to the next level.

"There are opportunities for people to come through the rankings and make a push into the higher levels of the game - it is just about their attitudes and results - Ross and Jamie could be next."

Hutchins has vowed to grasp his possible Davis Cup opening with both hands as he looks for his partnership with Auckland to continue blossoming on the international stage.

"I want to keep giving John Lloyd difficult decisions to make and I know that's up to me to produce," said Hutchins.

"Jamie Murray has really shown what can be achieved in doubles and hopefully it will be my turn to produce in 2008."
