The pursuit of perfection in tennis has proved beyond all but one player in the modern era, Germany’s Steffi Graf.
During her 17-year career Graf collected 22 Grand Slam singles titles and spent a record 377 weeks as world number one.
Yet when reviewing Graf’s impact on her sport, there is only one place to start — 1988.
It was the year a 19-year-old Graf won the Australian Open, French Open, Wimbledon, U.S. Open and Olympics. The Golden Slam.
American Serena Williams now owns a modern-era record 23 Grand Slam singles titles and Roger Federer is, for many, the greatest player, man or woman, to wield a tennis racket.
