The other thing about Frazier is that tennis isn't the be all and end all for her. She plans to become a school teacher (teaching maths, no less) after she retires, and she has a very honest outlook on her talent and her accomplishments. I think the absence of a "tennis or nothing" attitude shows in her game - she's grateful to the sport for giving her the opportunity and the financial stability that will enable her to go back to school and acquire the training needed to become a teacher, but at the same time, she's honest enough with herself to recognise and accept that she'll never be a top player.
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)
