World number one players Roger Federer and Victoria Azarenka will head the list of seeded players in the draws for the London Olympics' tennis tournament.
The draw will be held at Wimbledon on Thursday for the star-packed tennis competition beginning Saturday, Xinhua reports.
Each of the singles tournaments has 64 competitors, with 16 seeds based on the world rankings of June 11.
Reigning Wimbledon champion Federer aims to win his first Olympic singles medal, having captured mixed doubles gold with Stanislas Wawrinka at the 2008 Beijing Olympics.
Second-ranked Novak Djokovic is the defending bronze medallist and fourth-ranked Andy Murray looks to win a medal on home soil.
Reigning gold medallist Rafael Nadal was forced to withdraw from the event with knee tendinitis.
In women's category, Belarussian Azarenka will lead the pack of top ten players in the prestigious event to be held at All England Club.
The doubles events will each contain 32 teams, with eight seeded pairs selected at the discretion of the International Tennis Federation (ITF).
If there are two players or doubles teams from the same National Olympic Committee (NOC) in any event, they will be drawn in opposite halves of the draw. If there are three or four players or teams from the same NOC, they will be drawn into different quarters of the draw.
The draw for the 16-team mixed doubles, based on the rankings of June 11, will be held July 31.
Players can only enter the mixed doubles event if they are competing in at least one of the other four events.
