ELENA BALTACHA is likely to be the first British player in action when the tennis starts at Wimbledon today.

The Scot is due to meet Hungary's Agnes Szavay in the first round of the Olympic women's singles in the third match on Court 18, scheduled for around 3.30pm.

The world No.102 has struggled for form this season but Szavay has played only one match in more than a year because of back problems and does not even have a world ranking.

Baltacha said: "It's a good draw for the first round. You can't take anyone lightly but hopefully I can go out and do my thing and get into the second round. I'm feeling good and I'm feeling ready."

She added: "I can't believe how quickly the time's passed and it's all kicking off. It's an amazing feeling to be part of it and I can't wait to start my match."

The Murray brothers begin their men's doubles campaign fourth on Court Two against Austria's Jurgen Melzer and Alexander Peya, with Andy Murray facing Stanislas Wawrinka of Switzerland in the singles tomorrow. Linlithgow's Colin Fleming and Ross Hutchins are last on Court 14 against French duo Richard Gasquet and Julien Benneteau.

The British women also received a boost with the confirmation Laura Robson will play in singles as well as doubles, giving the hosts a full complement of four players in the former.

The 18-year-old has been first alternate since her doubles partner Heather Watson replaced Alona Bondarenko on Tuesday and was given a place in the competition when Croatia's Petra Martic withdrew with a foot injury yesterday.

Robson slots into the draw in the bottom half and will play the Czech Lucie Safarova tomorrow, with the carrot of a probable second-round meeting with Maria Sharapova, the No.3 seed.

Robson plays her first match tonight in the women's doubles. She and Watson take on the fifth seeds, Angelique Kerber and Sabine Lisicki from Germany.

Anne Keothavong has the toughest draw of any of the British players, facing the former world No.1 Caroline Wozniacki this evening, but she is at least rewarded with an appearance on Centre Court.
