Steffi Graf had a very difficult father, but she was lucky enough to have a supportive, caring, and understanding mother who stayed out of the limelight. Oh, and no list of supportive mothers can be complete without a mention of Colette Evert, Esther Seles, Marisa Vicario, and Oracene Price.
Best left-right combination by a German (and that includes Max Schmeling): Steffi Graf. All she did in 1987 was knock Navratilova out of #1 and try to knock Evert out of the sport. (Mike Lupica in "The Best and Worst of Tennis in 1987", World Tennis)
"A couple of years ago, we nicknamed Steffi Graf's forehand 'Jaws'. And that music would go perfectly when she starts running in to the net, swarming on that little ball." (JoAnne Russell, during the 1988 Wimbledon final between Graf and Navratilova)
