Sharapova made her professional breakthrough in 2004 at age 17, when she defeated two-time defending champion and top seed Serena Williams in the 2004 Wimbledon final for her first Grand Slam singles title. She entered the top 10 of the WTA Rankings with the win. Despite not winning a major in 2005, Sharapova briefly held the no. 1 ranking, and reached three Grand Slam semifinals, losing to the eventual champion each time. She won her second major at the 2006 US Open defeating then-world no. 1 Amélie Mauresmo in the semifinals and world no. 2 Justine Henin in the final.
Sharapova's 2007 season was plagued with a chronic shoulder injury and saw her ranking fall out of the top 5 for the first time in two years. She won her third Grand Slam at the 2008 Australian Open, defeating Henin in the quarterfinals and Ana Ivanović in the final. After reclaiming the no. 1 ranking in May 2008, Sharapova's shoulder problems re-surfaced, requiring surgery in October and forcing her out of the game for 10 months. Sharapova returned in May 2009 and was ranked no. 126 in the world due to her extensive lay-off. Since her comeback, Sharapova has won five singles titles (bringing her career total to 24) and improved her ranking to no. 2 in the world.
Sharapova has been featured in a number of modeling assignments, including a feature in Sports Illustrated Swimsuit Issue. She has been featured in many advertisements, including for Nike, Prince and Canon, and is the face of several fashion houses, most notably Cole Haan. Sharapova was the most searched-for athlete on Yahoo! in 2005 and 2008. Since February 2007, she has been a United Nations Development Programme Goodwill Ambassador, concerned specifically with the Chernobyl Recovery and Development Programme. In June 2011, she was named one of the "30 Legends of Women's Tennis: Past, Present and Future" by Time.
