Martina Navratilova v Chris Evert: Wimbledon Final 1978 (Extended Highlights)

What is so interesting for me about these two great players is how their careers spanned the early professional era of tennis playing alongside King, Court, Wade and Goolagong, then they saw off a host of younger players in the middle part of their careers, Austin, Mandlikova, Jaeger, and finally faced opponents such as Graf, Seles, Sanchez-Vicario. They achieved this by becoming faster, fitter and stronger. They oversaw the transition from Wood to Graphite. They started as good stroke players with less physical strength and fitness and ended up as great and stronger athletes. They helped transform the sport and paved the way for the new era of tennis we have today.
