Ana Schweinsteiger (born 6 November 1987 and professionally known by her birth name Ana Ivanovic), is a Serbian former world No. 1 tennis player. She gained the top ranking in 2008 after she won the 2008 French Open, and held it for a total of 12 weeks. She was also the runner-up at the 2007 French Open and the 2008 Australian Open, losing to Justine Henin and Maria Sharapova respectively. She qualified for the year-end WTA Tour Championships three times, in 2007, 2008 and 2014 and won the year-end WTA Tournament of Champions twice, in 2010 and 2011. Ivanovic won 15 WTA Tour singles titles, and one Grand Slam singles title, the French Open in 2008. Additionally during this time, she earned over $15.5 million in prize money, which is the 25th highest in the all-time rankings. In June 2011, she was named one of the "30 Legends of Women's Tennis: Past, Present and Future" by Time and was also included on the list of "Top 100 Greatest Players Ever" (male and female combined) by reporter Matthew Cronin.

By the age of 18, Ivanovic had already defeated established players such as Svetlana Kuznetsova, Nadia Petrova, Vera Zvonareva and Amélie Mauresmo. Ivanovic was known for her aggressive style of play and impressive forehand, described by Petrova as "the best out there." Ivanovic's struggles after winning the 2008 French Open were well documented. After that victory, she was overwhelmed by attention and endured an ongoing period of reduced success, failing to make a Grand Slam quarterfinal in her subsequent 17 Grand Slam tournaments, and dropping as low as No. 65 in the rankings during July 2010. In 2012, Ivanovic reached her first Grand Slam quarterfinal since her French Open victory at the 2012 US Open, thereby achieving the feat of reaching the quarterfinals at all four Grand Slam tournaments, and finished with a year-end top 15 ranking for the first time since 2008. In 2014, Ivanovic enjoyed a resurgence, beginning with her victory in the Auckland Open, her first singles title in over two years, before going on to win the Monterrey Open, Aegon Classic and the Pan Pacific Open. She qualified for competition in the WTA Tour Championships and secured a year-end ranking of No.
