Steffi Graf

Born: June 14, 1969

Born in Mannheim, Baden-Wurttemberg, West Germany

Resides: Las Vegas, Nevada

Turned pro: 1982

Able to win on all surfaces, Graff was a model of consistency throughout her 17-year career. Her record 377 weeks ranked as number one in the world is a record for any player, male or female. In 1988, Graff became the first player to achieve what is regarded as the calendar year Golden Slam by winning all four majors plus the Olympic Gold Medal in the same year, a remarkable feat.

From the late 1980s to the mid-1990s, there was no one better than Graf, and when she retired in 1999, she was still ranked number three in the world. Were it not for the long and storied career of Serena Williams the case would be made for Graf as the greatest of all-time. While many will continue to debate Steffi versus Serena as the greatest female player of all-time they were both incredible players who dominated their era and advanced women’s tennis.

One of the strongest and most powerful women to ever play the game, Serena Williams has certainly left her mark on tennis. Together, Serena and her sister, Venus, have been a dominant force in women’s tennis since the late 1990s. With 23 Grand Slam Singles titles including the 2017 Australian Open, Serena now owns the open era record for Grand Slam singles titles by a tennis player, male or female.

Serena’s game has certainly withstood the test of time and competition. Her Grand Slam titles have come over an 18-year period starting in 1999, with her latest victory coming at the 2017 Australian Open. Out of competitive tennis for most of 2017 while pregnant, Serena has now reached 4 Grand Slam finals without securing that coveted 24th title. Certainly making it to the 2018 and 2019 Wimbledon and US Open finals was a step in the right direction and everything points to Serena remaining competitive despite turning 38 in 2019.
