Dudi Sela's preparations for Wimbledon got off to the worst possible start on Monday when he lost in the first round at the Queen's Club in London. Israel's No. 1, who dropped four places to No. 65 in the world on Monday morning, suffered a 4-6, 4-6 defeat to Serbian Viktor Troicki (100), exactly two weeks before the start of the year's third Grand Slam at the All England Club. Tzipi Obziler, who plummeted 27 places to No. 120 in the world, also suffered a first round exit on Monday, losing 5-7, 3-6 to Aiko Nakamura of Japan in Birmingham. Shahar Pe'er fell out of the world's top-20 for the first time in 18 months on Monday, dropping seven places to No. 25 following her first round exit at the French Open. Pe'er's match against Nuria Llagostera Vives in the first round of the Torneo Barcelona KIA on Monday was suspended because of darkness with the score tied at 5-5.
