Serena Williams: US Open champion's career in numbers
Serena Williams edged even closer to the most successful female tennis players of all time by winning the US Open on Sunday.
The victory was the world number one's 17th Grand Slam title - only Martina Navratlova, Chris Evert, Steffi Graf and Margaret Court have won more than the American.
At 31, Williams claims to have never felt better and has no plans to retire any time soon.
BBC Sport takes a look at the numbers behind the woman who Victoria Azarenka, beaten in the final by Williams on Sunday, believes is "the greatest of all time".
Williams chases the records
- Williams's US Open win puts her within five Grand Slam titles of Steffi Graf's Open era record of 22. She is seven short of Margaret Court's all-time record total of 24.
- She is only the fourth female in the Open era to have competed in at least 20 Grand Slam finals. The other three are Navratilova, Evert and Graf.
- Since a first-round exit at the 2012 French Open, Williams has won four of the past six Grand Slam tournaments.
- Only Navratilova (306), Evert (299) and Graf (278) have won more Grand Slam matches in the open era than the 246 victories accumulated by Williams.
- Her victory against Victoria Azarenka at Flushing Meadows on Sunday also made her the first top-seeded champion at the US Open since Justine Henin in 2007.
- It was her fifth US Open title. She has also won both the Australian Open and Wimbledon on five separate occasions, while she has claimed the French Open title twice.
- Williams has yet to win all four Grand Slams in a single season, but came close in the 2002 when she won three titles - the French Open, Wimbledon and US Open. Her 2003 Australian Open triumph was her fourth straight major - a feat that was labelled the "Serena Slam".
Williams on the WTA
- She has won 55 Women's Tennis Association singles titles in total. Graf, who retired in 1999, won 107 singles titles while Court holds the all time women's record of 192 singles titles.
- Since turning professional in 1995, Williams has 621 wins and only 112 losses. Graf won 902 of her 1017 matches over the course of her 17-year career.
- Williams's win percentage currently stands at 84.72%. Court, who played both before and during the open era, has the highest singles career winning percentage in the open era with 91.37%.
- Williams has a career-best nine titles in 2013 but has some way to go to beat the all-time record of singles titles won in a one year - Court won 18 back in 1973.
- At 31, Williams is a year older than the age Graf was when she retired in 1999. Court played on until she was 35, retiring in 1977.
- Williams has spent a total of 153 weeks at number one in the WTA rankings, placing her 12th in the all-time list. Graf tops the standings with 377 weeks at number one.
- Williams's longest run of consecutive weeks at number one stands at 57 - from 8 July 2002 to 11 August 2003. Graf holds the record, having spent 186 weeks in a row at the top of the list.
- Williams, along with her sister Venus, holds the record for the most gold medals won by tennis players at an Olympics. She won doubles gold with her sister in the 2000, 2008 and 2012 Olympics, while she won a singles gold medal in London last year, taking her total to four medals.
- Only Kitty McKane of Britain has won more Olympic tennis medals than the Williams sisters. McKane won five medals in total from the 1920 and 1924 Olympics - one gold, two silver and two bronze medals.
The power behind the success
- Williams's fastest serve in Sunday's US Open final was 126 miles per hour, three miles per hour faster than Rafael Nadal's fastest in his semi-final win over Richard Gasquet.
- Her fastest-ever serve is 128.6mph - achieved in this year's Australian Open. That serve is the second fastest-ever in women's tennis at a Grand Slam tournament. Her sister Venus holds the world record, having achieved a speed of 129mph at the 2007 US Open.
- In 2013, Serena Williams has served 419 aces and won 74.8% of her first-serve points.
On the money
- Williams's earnings for 2013 currently stand at £5.8m - the most she has earned in a single year to date.
- She tops the money list for career earnings, having amassed a total £32.5m in prize money over the course of her career so far. Venus is second in the money list, having earned £18.4m.
- Graf earned £13m in prize money over the course of her career, while Navratilova earned £12.9m. Evert, the first female player to earn one million dollars in a year, made a total of £5.6m over the course of her career.
