Svetlana Aleksandrovna Kuznetsova is a Russian former professional tennis player. She is a two-time major singles champion, winning the 2004 US Open and 2009 French Open, and finishing runner-up at two other majors. In doubles, Kuznetsova reached the finals of each major at least once, winning the Australian Open twice. Kuznetsova moved to Spain at the age of seven to attend the Sanchez-Casal Academy. In 2001, she first took part in a WTA Tour tournament, the Madrid Open, and a year later won her first WTA Tour title at the Nordea Nordic Light Open in Helsinki, Finland. Her first appearance at a major was at the 2002 Australian Open, and her first major title came at the 2004 US Open over countrywoman Elena Dementieva, making her the third Russian woman to win a major title. Kuznetsova's second major singles title was the 2009 French Open, defeating compatriot Dinara Safina in the final. At the 2006 French Open and the 2007 US Open singles tournaments she was the runner-up, both times to Justine Henin. As a result, Kuznetsova obtained a career-high WTA ranking of world No. 2, holding that position for 24 weeks in 2007 and 2008. After the 2010 season, Kuznetsova lost her top 10 position and dropped down to a year-end ranking of 72 in 2012, until recovering gradually through 2016, when she reentered the top ten and reached the semifinals of the WTA Finals, her best result in that tournament. Apart from singles tournaments, Kuznetsova was also successful in doubles. She won her first five WTA doubles titles with Arantxa Sánchez Vicario. After a series of disappointing results with her she paired with Martina Navratilova, Elena Likhovtseva, Alicia Molik, and Amélie Mauresmo. Pairing with Likhovtseva, she climbed to No. 3 in doubles in 2004, holding that position for eight weeks, her career-high. She won the Australian Open twice in doubles, in 2005 alongside Molik and in 2012 partnering Vera Zvonareva. Kuznetsova also played various mixed doubles events, most prominently in 2003, but never went beyond the quarterfinals. Over her career, she won a total of 18 singles and 16 doubles titles.
