体坛英语新闻：Djokovic, Tsonga have wobbly starts on historic day

LONDON, July 29 (Xinhua) -- Serb Novak Djokovic, the second seed and bronze medallist at Beijing 2008, dropped a set in his first-round match on an historic day at the London 2012 Olympic Games tennis tournament at Wimbledon, where play took place indoors for the first time in the Olympics in the modern era as the Centre Court roof was closed after heavy rain on Sunday.

Thirty matches scheduled for Sunday were postponed due to the heavy rain while four other matches were suspended and will be completed on Monday.

Djokovic, the world No.2 and flag bearer for Serbia at the Opening Ceremony on Friday night, dropped the first set in his match with Fabio Fognini of Italy but went on to win 6-7(7), 6-2, 6-2. The two players had met twice before, on clay and hard court, and both times Djokovic won in straights sets.

Frenchman Jo-Wilfried Tsonga, the fifth seed and Wimbledon semifinalist, also dropped the first set in his match with Tomasz Bellucci from Brazil, but eventually won at 6-7(5), 6-4, 6-4 in what was their first encounter on any surface.

Australian Bernard Tomic, the Australian No.1, was defeated by 15th seed Kei Nishikori of Japan 7-6(4), 7-6(4). Tomic had four set points in the first set that he failed to convert and this defeat brought his losing streak to seven matches.

Andy Murray started his campaign to become the first Briton to win an Olympic Games medal since Tim Henman and Neil Broad, who won silver in the men's doubles at Atlanta 1996. He took just 89 minutes to defeat Stanislas Wawrinka of Switzeland 6-3, 6-3. This brought Murray's winning record against the Swiss to seven out of 11 meetings on three surfaces.

In women's singles part, Agnieszka Radwanska of Poland, the world No.2 and second seed, lost her first-round match to Julia Goerges from Germany, the world No.24.

Radwanska, who was runner-up to American Serena Williams at this year's Wimbledon and was Poland's flag bearer at the Opening Ceremony, was broken in her first service game and lost the first set. She came back to take the second set on a tiebreak, but eventually lost 7-5, 6-7(5), 6-4.

The Radwanska-Goerges match was the first on Centre Court and for more than two hours was the only tennis being played at Wimbledon as play on the outside courts was suspended due to heavy rain. It marked a historical moment, as it was the first tennis match at an Olympic Games in the modern era to be played under cover after the Centre Court roof was closed.

Russia's third seed Maria Sharapova raced to a 65-minute win over Shahar Peer from Israel at 6-2, 6-0. Sharapova has now defeated the Israeli in each of their seven meetings on three surfaces.
