Barker won Brighton beating US champion Tracy Austin along the way. It gleaned considerable press at the time. As I said before, she could be amazing to watch. Very popular in Australia apparently. Her forehand was anything but second rate. Graf did have the benefit of modern technology.
And Barker appears very happy in life, incredibly successful presenter (the lynchpin of BBC London Olympics). I'd say she is a winner in life- something I'm not sure that many of her contemporaries are? The girl's done good.
Whoever said, "It's not whether you win or lose that counts," probably lost.
