Reshika in action today

Dinesh Weerawansa - Reporting from England

Sri Lanka's Reshika Udugampola has been drawn in heat two of women's 100m freestyle first round heats of the London 2012 Game to be worked off at Aquatic Centre here today. She will compete in lane seven of women's 100m free style heat two with Gayana's Britani Van Lange on her right. All in all, there are 48 women who will compete in the qualifying round which consists of seven heats.

Of the 48 competitors who will be in action today, FINA World championship bronze medallist and Beijing 2004 4 x 100m relay silver medallist Ranomi Kromowidjojo accounts for the best entry timing of 52.75 seconds. She will compete in the last of the seven heats.

Udugampola, who has been training in Melbourne, has been shaping well in recent months and is determined to make the best use of the opportunity she has got. “I know this is a rare opportunity to compete at the highest level. It will be a tall order but I will make every effort to better the Sri Lanka record and make my presence felt,” Udugampola said on the eve of her big event.

Teenage Meilutyte claims gold

There has been tremendous interest and enthusiasm on London Olympics swimming competition which will offer a total of 950 swimmers competing for 36 gold medals. Teenage sensation Ruta Meilutyte claimed a sensational gold medal for Lithuania in the women's 100m Breaststroke on Monday night.

The 15-year-old led from start to finish to touch in one minute and 5.47 seconds as she held off a fast-finishing Rebecca Soni, the Beijing silver medallist. Japan's Satomi Suzuki claimed the bronze. An emotional Meilutyte was shocked at the end of her record-breaking performance when she said “I can't believe it. It's too much for me,” she said,

USA's Matt Grevers set a new Games record as he claimed gold in the men's 100m backstroke, an event in which Sri Lanka's Heshan Unamboowe was eliminated after the first round heats. Grevers clocked 52.16 seconds, with compatriot Nick Thoman (52.92) claiming the silver medal and Japan's Ryosuke Irie (52.97) bronze.

Ye Shewin returned to the Olympic pool after her super-fast 400m individual medley swim to easily head the field in the heats of the shorter medley event.

But the star attraction in fourth day's action of the XXXth Olympiad was world number one in tennis - Roger Federer, who cruised into the third round of the men's Singles tournament with victory over Julien Benneteau at Wimbledon. Federer was untroubled in a 6-2 6-2 victory on Centre Court.

“I had a good time on court. I thought the atmosphere was good,” he said after the match. The top seed is the reigning Olympic doubles champion with Stanislas Wawrinka but, were he to win Singles gold, he would be following countryman Marc Rosset, the surprise winner at Barcelona 1992.

Federer, who next meets Uzbekistan's Denis Istomin, added: ‘I definitely get inspired by the 1992 victory by Marc Rosset. That was huge news in Switzerland. “But I'm still very far away from all the medals in Singles and Doubles. Let's not get carried away too quickly. I'm happy with my level of play,”. The standout second-round match tomorrow will see second seed Novak Djokovic, who struggled a little bit against Fabio Fognini, face former world number one Andy Roddick.

The American, who is unseeded here, came through a tight clash with Slovakia's Martin Klizan 7-5 6-4 while another old stager, Australia's Lleyton Hewitt, dug out a 6-3 4-6 6-3 victory over Ukraine's Sergiy Stakhovsky. There was disappointment for Novak Djokovic, though, as he and Serbian partner Viktor Troicki were beaten 7-6 (10/8) 6-3 by Swedes Johan Brunstrom and Robert Lindstedt.

Records tumble in Weightlifting In weightlifting, Kim Un Guk triumphed to win gold in style for North Korea in an exciting men's 62 kg event which saw Olympic and world weightlifting records tumble. The pre-competition build-up was dominated by talk of a duel between Kim and Chinese rival Zhang Jie, with the duo sparring for world titles over the last two years.

But Zhang was pushed into fourth place as in-form Oscar Albeiro Figueroa Mosquera, from Columbia, took silver ahead of Indonesia's Irawan Eko Yuli on a lighter bodyweight after tying with their final totals. Kim followed up a snatch of 153kg, which broke the Olympic record and equalled the world best, with a clean and jerk of 174kg, providing him with a stunning personal best total of 327, which also eclipsed both records. The Olympic record for clean and jerk also fell at ExCel as Figueroa Mosquera lifted 177kg to help rack up a total of 317kg, level with Eko Yuli, who had to settle for bronze again after doing so four years ago.

In volleyball, the USA turned on the style in women's tournament as they scored a comprehensive 25-18, 25-17, 22-25, 25-21 win over defending champions Brazil.Chasing what would be a first gold in 10 attempts, Hugh McCutcheon's side were almost faultless in front of a boisterous crowd, sending out the clearest of signals that 2012 could be their year.

Backed by the support of USA Basketball star Kobe Bryant - off-duty this afternoon - they got to grips with Brazil's delicate style before blowing them off the court by way of the brilliance at the net of Destinee Hooker and Foluke Akinradewo.

With Brazil struggling to get to the floor - especially with American's exceptional libero Nicole Davis dealing with all that came her way - they found themselves under increasing pressure and, after falling 12-11 behind, were never ahead again in the first set.
