Andy Murray is leaving no stone unturned in his desperate effort to get into the shape but his wrist injury threatens to mar his show in this year’s Wimbledon, which kicks off on Monday. British number one Murray had a practice session with a sparring partner under the watchful eyes of coach Brad Gilbert and though the youngster hit the ball with force, it was clear that he has not recovered fully from the injury, which he had sustained in the Hamburg Open last month. Murray has already been advised by world number one roger Federer not to play if he is not fully fit. Wimbledon referee Andrew Jarrett has already made it clear that he would not entertain any request to allow Murray a Tuesday start, thus giving the youngster an extra day to recover. In case Murray plays and wins his first two rounds, the eighth seeded player would face fellow Briton Tim Henman, provided Henman too triumphs in his first two matches. Henman seemed eager to meet his compatriot and said I would love to play Andy in the third round, but that would mean having to win my first two matches, and that’s the most important thing. Henman, however, faces tough challenge in the first round where he has been pitted against former world number one Carlos Moya.
