I just found one very interesting and one very disturbing fact about Stefan Edberg on Wikipedia. I hope you find this interesting. First one is: Stefan's service motion is used on the Australian Open logo. If you notice, the figure on it has the same pronouned knee bend and arm motion. Second one is: Edberg was involved in a freak accident during the boys' singles final at the 1983 U.S. Open, when Richard Wertheim, a linesman, was struck in the groin by a ball struck by Edberg. Wertheim fell backwards, fracturing his skull, and died in hospital shortly thereafter. Second one threw me off. Was Stefan really involved in this fatal accident? It could explain why he rarely smiles and usually keeps a serious outlook.
