Andy Murray knocked out of Italian Open by Marcel Granollers Andy Murray endured a miserable 26th birthday as he retired from his Italian Open second-round tie against Marcel Granollers with a hip injury. The Briton looked troubled throughout and now faces a battle to be fit for the French Open which starts on 26 May. Spain's Granollers eased to the first set, winning 6-3, and led 2-1 in the second before Murray needed treatment. Murray battled back to win the second set 7-6 but then withdrew before the decider to hand Granollers victory. The world number two's exit was a surprising conclusion to a remarkable second set between the pair on the clay surface in Rome. Granollers, ranked 37th in the world, dominated the opening set as Murray struggled to find any rhythm, his repeated failure to find the necessary depth with his shots allowing the Spaniard to attack the net. Granollers's confidence grew visibly following the first set and he broke Murray again in an epic second-set opener that went to 10 deuces. Things looked even worse for Murray when he required on-court treatment after the third game of the second set. The Scot cut a dejected figure as he lost 10 consecutive points following his enforced break for treatment - but momentum then started to swing between the pair. Murray trailed 4-1 in the second set before showing great determination to reduce Granollers's lead to 4-3 and put pressure on the Spaniard for the first time in the match. Nerves appeared to affect the 27-year-old as he aimed for a first victory against Murray in three attempts and the British number one, now appearing to move more freely, took advantage to level at 4-4. Granollers broke Murray's serve in the ninth game, but failed to serve out the match in the 10th and with conditions becoming increasingly testing, with swirling winds whipping around the court, the set went to a tie-break. Murray, who has never won a title on clay, levelled the match when Granollers pushed a forehand long before retiring - to the amazement of Granollers and the Rome crowd.
