US Open champion Stosur out of Wimbledon June 27, 2012 -- Updated 1835 GMT (0235 HKT) Arantxa Rus celebrates her second round women's singles victory over Australia's Samantha Stosur on day three of the 2012 Wimbledon Championships US Open champion Sam Stosur loses to unseeded Dutch player Arantxa Rus at Wimbledon Defeat leaves Australia without a player in either singles championships Heather Watson becomes first British woman for 10 years to reach third round Italy's Sara Errani completes first-round win without hitting a ball (CNN) -- US Open champion Sam Stosur suffered another early Wimbledon exit as she crashed out to unseeded Dutch player Arantxa Rus. The fifth seed's surprise exit means there are no Australian players remaining in either singles championships at Wimbledon. Defeats for Lleyton Hewitt, Bernard Tomic, Matthew Ebden and Marinko Matosevic meant Australia were left without a player in the men's second round for the first time in 1938. Rus's 6-2, 0-6, 6-4 win means Stosur joins Casey Dellacqua, Ashleigh Barty, Anastasia Rodionova and Jarmilia Gajdosova in making a hasty exit from the women's draw. Rus, ranked 72 in the world, had never won a match in the main draw before this year's championships. She said: "I'm very happy with this win, especially won the grass." British records were broken too, but for all the right reasons as 20-year-old Heather Watson became the first British woman to reach the third round for 10 years. Watson walked on to Centre Court wearing headphones and deep in thought, but was soon tuned into the home crowd's enthusiasm for a British player. She cruised to a 6-1, 6-4 in over American Jamie Lee Hampton to move past the second round stage of a Grand Slam event for the first time. She said: "I always knew I could play this well, that ld get far in these tournaments, but it's different playing like that in practice from bringing it onto the match court at big occasions with pressure." German 15th seed Sabine Lisicki lost the first set to Serbia's Bojana Jovanovski before recovering to win 3-6, 6-2, 8-6 while Japan's Kimiko Date-Krumm, the oldest player at the tournament at 41, lost 5-7 6-3 6-3 to Ukraine's Kateryna Bondarenko in her first-round match. But Italian Sara Errani made it through to the second round without having to hit a ball on Wednesday. Her match with American Coco Vandeweghe was halted by rain on Tuesday, with Errani standing at match point. When they resumed on Wednesday, twice served into the net to double fault and secure a 6-1, 6-3 victory for Errani.
