Tamarine Tanasugarn

During her junior career, her expenses were provided by her father, Virachai Tanasugarn, a lawyer who was once a Thai basketball player and who inspired Tanasugarn to become a professional tennis player. At 17, she reached the Junior Grand Slam final at Wimbledon in 1995 with a win over Anna Kournikova in the semifinal, but lost to Poland's Aleksandra Olsza in the final, in straight sets.[10]

Tanasugarn turned pro in 1994, but made her WTA Tour debut in the 1993 Pattaya Open, in which she lost to Australian Rennae Stubbs. The following year, she made the second round in the same tournament by beating world No. 44, Marianne Werdel Witmeyer, in the first round.

1998, Tanasugarn reached the fourth round of a Grand Slam at the Australian Open by defeating the reigning French Open champion and world No. 6, Iva Majoli, 6–0, 6–2 in the third round. Tanasugarn also made her second fourth round of the year at Wimbledon, where she eventually lost to Martina Hingis. In 1999, she reached the fourth round at Wimbledon for a second time by defeating Frenchwoman Sandrine Testud, in the third round. Tanasugarn ended the year ranked No. 72.[11]

She partnered with Paradorn Srichaphan at the Hopman Cup in 2000. Tanasugarn beat Jelena Dokić of Australia, Barbara Schett of Austria, Ai Sugiyama of Japan, and Henrieta Nagyová of Slovakia. However, Tanasugarn lost in the women's singles final to Amanda Coetzer of South Africa, 6–3, 4–6, 4–6, having led 6–3, 3–0. In the men's singles final, Paradorn Srichaphan lost to Wayne Ferreira, 6–7, 3–6. This result made them the first Asian team to reach the finals at the Hopman Cup.

Tanasugarn reached three semifinals at the Japan Open, Kuala Lampur, and Shanghai. She represented Thailand in the 2000 Summer Olympics, but was defeated by Venus Williams.

Tanasugarn had to deal with multiple injuries, which affected most of her year in 2005. Her ranking dropped out of the top 100, and she played in Challenger-level tournaments to collect points.

In 2006, she once mentioned retiring from tennis, but, after she qualified to play in the main draw of Wimbledon and reached the third round, she decided to give it another shot. Tanasugarn reached her home country tournament final again in the Bangkok Open, facing Vania King, and was two games away from taking the title. Leading in the final set 4–2, King fought back to win the match. Despite losing the match, Tanasugarn regained some confidence to get back to the tour. She finished that year ranked No. 75.

Unfortunately Tanasugarn still struggled with injuries in 2007 and had to play in many Challengers, ending the season ranked No. 124.

She made a successful comeback in 2008. Tanasugarn decided to skip the clay-court season due to her difficulty playing on that surface and chose to play in hardcourt Challengers, she thought were more like grass. Tanasugarn won the singles title at the Kangaroo Cup in Gifu, defeating former world No. 4, Kimiko Date-Krumm.

In the grass-court season, Tanasugarn beat the Austrian Tamira Paszek in Birmingham, but lost to Bethanie Mattek in the fourth round.

It was the first time that Tanasugarn (as well as Erakovic) had advanced to the semifinals of a Grand Slam event in any capacity.
