"Able to win on all surfaces, Graf 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."
