When it comes to Grand Slam Champions, no other country in the world has produced more than the United States of America. Americans also have won more Grand Slams than athletes of any other country - and this is not just restricted to singles, but extends to doubles and mixed doubles as well.
Breaking it down to numbers: At Wimbledon, American men have won 32 Grand Slam titles since 1877 (second highest after host Great Britain), while American women have won a record 57 titles at the All-England Club.
Coming to the Australian Open, American men are second on the list with 18 trophies behind Australia. American women likewise are second behind Australian ladies with 24 titles.
At Roland Garros, male American players have won 11 titles till date (joint-third with Australia) and its female players have won 29 titles (only one behind hosts France). However, in the Open Era, American women lead the pack with 15 titles.
At the US Open, the dominance of American athletes can be visibly seen in the stats. Although the last American male player to win the US Open was Andy Roddick way back in 2003, its men have dominated the tournament since the inception, winning a total of 85 titles. In the women's draw, the numbers are even more staggering, with American women having won 92 titles; that is 86 titles more than the next best, Germany and Australia.
Here, we highlight the achievements of 10 of the greatest American tennis players of all time:
#10 Arthur Ashe
Arthur Ashe is an all-time great American legend who won the first US Open held in the Open Era in 1968. Ashe broke many stereotypes and barriers - from being the first black tennis player to get selected to the US Davis Cup team, to being the first black player to win a Grand Slam title.
Ashe received the USA's highest honour - the Presidential Medal of Freedom, posthumously in the year 1993 from President Bill Clinton. The primary court of the US Open at the Billie Jean King Tennis Center, New York is named after him.
Ashe won a total of 3 Grand Slam titles but more than this, his amazing story is what inspires millions.
#9 Althea Gibson
The foremost black player to compete on the women's tennis circuit in the 1960s was American Althea Gibson. At a time when racism and prejudice were widespread in sports and society in general, Gibson achieved considerable success. and is an inspiration to many young players to this day.
She was the first ever black player to win a Grand Slam, and her contributions are spoken of in high regard even today.
"Her road to success was a challenging one," said fellow American tennis great Billie Jean King about Gibson's career. Venus Williams and Serena Williams have often spoken about the kind of impact Gibson's success had on their own careers early on.
Gibson was a five-time Grand Slam Singles champion, winning Wimbledon and the US Open twice each and the French Open once. If Gibson had won the Australian Open, she would have become the fourth woman at the time to complete the Career Slam.
#8 Venus Williams
The only player in tennis history to win Olympic medals in 4 different Summer Olympic Games, big-serving American Venus Williams has been a mainstay of women's tennis for almost 20 years.
Venus Williams has won 7 Grand Slam Singles titles, 14 Grand Slam Doubles titles, 2 Mixed Doubles titles and 5 Olympic medals, of which 4 are gold. She is second only to her younger sister Serena Williams in career prize money earnings.
If not for her sister Serena, Venus would have won the French Open and Australian Open too.
Making her first Grand Slam singles appearance at the 1997 French Open, Venus has appeared in a record 80 Grand Slam tournaments, which is the highest among both men and women. At 38, Venus Williams still has the hunger and desire to compete at the highest level, and is eagerly looking forward to the 2019 tennis season.
#7 John McEnroe
John McEnroe, Jr. is a former World No. 1 tennis athlete often rated among the greatest tennis players of all time, especially for his silken skills at the net.

McEnroe was known for his shot-making ability and volleying skills, for his rivalries with Björn Borg, Jimmy Connors and Ivan Lendl, and for his confrontational on-court behavior with umpires which frequently landed him in trouble.
McEnroe is one of the most underrated doubles players of all time. Despite winning 9 doubles titles most of them with Peter Fleming, his doubles game is almost never spoken about.

Tilden brought an intellectual approach to tennis. He thoroughly studied and mastered the use of spin, favored drop shots and lobs, and would rely on his athleticism and physical build to wear his opponents down.
Tilden was ranked World No. 1 for a record six consecutive years between 1920 and 1925 - a feat that was later matched by Pete Sampras 73 years later in 1998. Tilden didn't lose a single match in all of the year 1924.

In 1973, King was at the forefront of the formation of the Women's Tennis Association (WTA). Utilising her position as one of the game's champion players, she threatened a boycott of the 1973 US Open if the issue of pay disparity was not addressed.
Her demands were eventually met, and the the US Open became the first Grand Slam to offer equal prize money to women and men. The USTA National Tennis Center in Flushing Meadows, New York City was named in her honour as the USTA Billie Jean King National Tennis Center.
Inducted to the International Tennis Hall of Fame in 1987, King continues to remain closely associated with the sport of tennis as an analyst and as a television commentator. She also served as captain of the US Olympics team at the 1996 Atlanta and 2000 Sydney Games.
