Israel's wheelchair tennis players swept through their matches at the London Games on Sunday, including three singles games and one doubles. Noam Gershony, Shraga Weinberg and Boaz Kramer all booked their spots in the quad singles quarterfinals, while Gershony and Weinberg advanced to the quad doubles semifinals.

Gershony had the toughest time, taking on local favorite and world number 5 Jamie Burdekin of Great Britain. Burdekin took the first set 6-3 before Gershony took control and won the final two sets by an identical score.

Weinberg dispatched of Swede Marcus Jonsson 6-1, 6-2. He said after the win that he was nervous during the first game because of the excitement of starting the competition. However, he added, after that he relaxed and played his "usual game."

Kramer knocked out Giuseppe Polidori of Italy 6-3, 6-2. "There was a lot of tension," he said Sunday after the match. "My opponent is very clever and it's hard to play against him. But I'm ranked higher than he is. I had to beat him and I won."

Medal hopes on the water sink

Weinberg and Jonsson also met in the doubles quarterfinal, as Weinberg and Kramer won both sets against Jonsson and fellow Swede Anders Hard 6-1, 6-4. The Israeli duo meet Americans Nicholas Taylor and David Wagner in the semis on Monday.

Israel's seafarers were less fortunate on Sunday.

Rower Moran Samuel finished fifth in the women's single sculls final. Having finished third overall in the heats, Samuel felt she had a shot at a medal.

But she crossed the 1,000-meter finish line in 5:48.67 seconds - 1.13 seconds behind bronze medalist Liudmila Vauchok of Belarus and only good enough for fifth place.

Olga Sokolov and Reuven Magnagey finished third in the Final B of the mixed double sculls, leaving them ranked ninth overall.

Israel's sailors also continued to trail. The best showing was fourth by Dror Cohen, Arnon Efrati and Benny Vexler in the 3-person keelboat (Sonar ) in Race 3. The trio then finished Race 4 in 10th place.

Shimon Ben Yakov and Hagar Zehavi finished 7th and 5th respective in Race 3 and Race 4, competing in the 2-person keelboat (SKUD 18 ).

Israel's swimmers return to action on Monday with Itzhak Mamistvalov pursuing his second medal of the games along with Iad Shalabi, Yoav Valinsky and Erel Halevi.
