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. The world no. 1 ranking followed in 2005, along with subsequent major titles at the 2006 US Open and 2008 Australian Open, before she was forced out of the game for ten months by a recurring shoulder injury, which ultimately required surgery in October 2008. Sharapova returned to the game in May 2009, returning to the top 10 in March 2011 and capturing her fourth Grand Slam title at the 2012 French Open. By doing so, she became the sixth woman in the Open Era to complete the career Grand Slam. In the same year, she won an Olympic silver medal in the London 2012 Olympics.
