Next week the ATP Tour lands in Eastbourne, England at the Aegon International.
This year the 22 year old, six feet three inches tall Murray could become the first Englishman to win Wimbledon since tennis legend Fred Perry in 1936.
Murray, under contract to wear Fred Perry tennis clothes, reached US Open final in September before losing to the world number two Roger Federer of Switzerland 6-2, 7-5, 6-2.
Then in January at Melbourne, Murray was favored to win his first grand slam title at the Australian Open before he was upset in the fourth round in five sets by Fernando Verdasco of Spain.
Earlier this month at the French Open, Murray lost the quarterfinals to Fernando Gonzalez of Chile in four sets.
In reaching the quarterfinals at Wimbledon last year, Murray recorded his best London result to date. However with the top ranked and defending Wimbledon champion Rafael Nadal of Spain undergoing treatment for a recent knee injury, the Wimbledon field could open up substantially.
It was Nadal who topped the Brit Murray in last year's Wimbledon quarterfinals 6-3, 6-2, 6-4.
Murray, the 189th ranked Alex Bogdanovic and the 199th ranked Joshua Goodall are the lone British players in the ATP Tour's top 200 players.
