The sporting world of tennis has some of the world's most beautiful and sexiest female tennis athletes. Recently, Sports Illustrated (SI) has round up the female tennis athletes, who have previously graced the magazine's swimsuit issue.

Several female tennis athletes have appeared on the swimsuit issue, although not on the front page.

Steffi Graf

Steffi Graf has appeared in the 1997 issue of SI Swimsuit. She started the trend for female tennis athletes. The shots were staged and taken in Cabo San Lucas, Mexico reportedly photographed by Walter Iooss. The 1997 SI Swimsuit Issue featured model Tyra Banks on the cover.

Serena Williams

Top-ranked athlete Serena Williams, who just won her 18th Grand Slam title at the 2014 US Open, has posed for SI Swimsuit in 2003.

Ana Ivanovic

Ana Ivanovic is the last female tennis player to appear on SI Swimsuit. She was featured on the 2010 edition. Ivanovic's appearance on the magazine has reportedly earned a lot of criticisms because shortly after she was featured, her performance on the tennis court deteriorated, which eventually led to her dropping out of the Top 50 in the World Tennis Association's (WTA) world rankings. Currently, Ivanovic is at the 10th place of the rankings. The cover of this issue was Brooklyn Decker.
