As we approach the end of Wimbledon fortnight the prospect of a grand slam final will have to remain a dream for Britain's tennis stars.

But for two up-and-coming Harrow players there is still an outside chance of a major win on home soil this year.

At the end of this month Marc McCarroll and Andrew Lapthorne will be looking to pit their wits against the world's best in the wheelchair tennis British Open.

Seventeen-year-old Lapthorne and McCarroll, 23, are preparing themseleves for the tournament in Nottingham after an extremely successful year.

In just his second campaign in the sport, McCarroll has risen through the ranks in astonishingly quick fashion.

Having won tournaments in France and Israel, the North Harrow born star has stormed up the rankings and now sits comfortably at 79 in the world and fifth in Britain.

He has beaten Britain's second and fourth highest ranked players along the way and put in great performances against some of the sports' elite.

Pinner boy Lapthorne on the other hand has just returned from playing for Great Britain in the wheelchair tennis equivalent of the Davis Cup in Italy, where he won all his rubbers except in the final. He now enters his final year as a junior and looks to better his already impressive junior rank of seventh in the world.

Although the pair admit their chances in this year's tournament are slim, with youth on their side it seems it is only a matter of time.

McCarroll, who had barely picked up a tennis racket before a car accident left him wheelchair bound a few years ago, said: "Everything seems to be going really well for both of us at the moment.

"We have been able to get valuable experience by playing some of the best guys and really competing with them. For me personally it has been great to know I can rally with these players and I think people have been really shocked by just how quickly I have pushed up the ranks."

The ex-Hatch End High School pupil added: "I think having not played tennis previously has helped in a strange way because I haven't had to adapt my game. Effectively I learnt how to play in a chair."

Lapthorne, who has Cerebal Paulsy, says that while every player dreams of winning a grand slam, it is the paralympics in London 2012 that they have really got their sights on.

He said: "Marc unfortunately just missed out on Beijing because of the ranking points, but we have both sat down and talked about wanting to do something memorable in four years' time.

"We had already set that year as a target before we knew it would be in London - but obviously that has just motivated us more.

"We don't want to be playing to make the numbers up though; we real-ly feel like we can go there and come away with medals."

But working to that target will be far from easy.

As it stands the pair are training six days a week for as long as nine hours a day. They train at top class facilities at the National Tennis Centre in Roehampton with the likes of Andy Murray, Tim Henman and Greg Rusedski, and compete around the world for a potential yearly prize fund of £1million.

This week they head to Switzerland for their last ranking tournament before the British Open on July 22.
