LONDON -- Roger Federer and 16 of the other top 20 men and Ana Ivanovic and 17 other top 20 women have entered the tennis tournament at next month's Beijing Olympics.
The International Tennis Federation used the ATP and WTA rankings as a guide to determine who gets the 56 direct spots in the men's and women's singles competitions. Six of the remaining eight spots in each tournament were given out by the ITF's Olympic Committee.
Each country, however, was limited to a maximum of six players in each tournament, with up to four competing in singles and up to two teams in doubles.
The Olympic tennis tournament runs from Aug. 10-17.
