LONDON - Andy Murray has warned the country’s tennis establishment that if the millions of dollars generated by Wimbledon are squandered, Britain may wait another 77 years to celebrate a homegrown champion. The Scot became the first British man since Fred Perry in 1936 to win the Wimbledon singles crown with his 6-4, 7-5, 6-4 victory over Novak Djokovic on Sunday. But amidst the hysteria and the congratulations, which poured in from Hollywood stars to Queen Elizabeth, Murray highlighted that the sport is still struggling in Britain. World No 2 Murray is Britain’s only player in the top 200. James Ward is the next best at 219 with Daniel Baker at 255 and Alex Bogdanovic, at 275, in the slipstream. Only Ward and Kyle Edmund joined Murray at Wimbledon but both were knocked out in the first round.
