Klára Koukalová

Koukalová made her Grand Slam debut at the 2003 Australian Open, defeating fellow qualifier and Grand Slam debutante Maria Sharapova in the first round, before going on to upset sixth-seed Monica Seles. Her run ended in the third round.

In January 2006, she played comeback player Martina Hingis, at the WTA Tour tournament in Gold Coast, where she lost in the second round. Koukalová was seeded 29th at the Australian Open, but lost in the first round to Ekaterina Bychkova. In that year, she had ten first-round losses in singles and failed to win a doubles match.

In 2008, Koukalová reached the final of the inaugural Cachantún Cup in Chile. She played the top seed Flavia Pennetta, but was forced to retire due to a sprained ankle. This also forced her to withdraw from the next tournament in Bogotá, where she had made the quarterfinals in 2007.

Koukalová's biggest win came at the 2009 Andalucia Tennis Experience in Marbella, Spain. She defeated world No. 1 and ten-time Grand Slam champion, Serena Williams, in three sets. Williams was also her first-round opponent at the French Open, Koulalová this time lost.

She gained another good win over a top-5 player, defeating Dinara Safina in the first round of the Madrid Open.

In the first round of the Warsaw Open, Koukalová caused a big upset by defeating fourth seed and world No. 14, Marion Bartoli. She was then defeated by world No. 205, Gréta Arn, in the second round.

At the Wimbledon Championships, Koukalová advanced to the fourth round for the first time at a Grand Slam. She scored upset wins over 18th seed Aravane Rezaï and tenth seed Flavia Pennetta, before falling to qualifier Kaia Kanepi.

Koukalová made the final at the Danish Open, where she lost to then world No. 3, Caroline Wozniacki. She defeated Rossana de los Rios, Tatjana Malek, Sorana Cîrstea, and Li Na en route to the final. After this tournament, she could not match her performance as she went on to do poorly in her last four tournaments, only advancing to the second round at Linz, where she lost to Patty Schnyder.
