Martina Hingis achieved success in the transition period between the sunset of Steffi Graf and the future rise of sisters Venus and Serena Williams. In her career she won a total of 43 WTA singles and 64 doubles titles, including 25 Grand Slams (5 singles, 13 doubles and 7 mixed doubles). At the age of 16, in 1997, she was the youngest tennis player in history to win Wimbledon and become world number one, as well as one of the greatest female tennis talents of the 90s.

Victim of several injuries and strong psychological pressures on his career expectations combined with her young age as a rookie, she announced her first retirement in 2003 at the age of just 23, to then return to competition two years later and retire again in 2007, devoting herself following her career as coach and captain of the Swiss Fed Cup team.

In 2013, the year in which she was inducted into the International Tennis Hall of Fame, she returned to professional tennis, however, only competing in doubles and mixed doubles. She obtained the Career Grand Slam in both specialties, winning all four Grand Slam tournaments at least once.

In singles she failed to win the Grand Slam due to the two defeats in the finals at Roland Garros: the first (won by Iva Majoli) in 1997, the year in which Hingis won the other three Slams, and the second in 1999 (won by Steffi Graff). She was harshly criticized for the way these defeats in Paris accrued, for a knee crippled by a fall on horseback on the eve of the tournament in 1997 and for a nervous breakdown during the 1999 final. She retired at the end of the 2017 season, when she was still number one in the world in doubles.
