It's Wimbledon time, so time for me to read a book about tennis, by far my favourite spectator sport. This book by a tennis journalist recalls the rivalry between these two giants of the tennis court that dominated the late 70s and early 80s, though really Connors has to be added as a third member of the triumvirate, albeit perhaps at a slightly lower level. In particular it focuses on their epic Wimbledon final of 1980, when Borg won his fifth consecutive title, but not before McEnroe had saved seven match points in a fourth set culminating in a titanic tiebreak which the American won 18-16. Often referred to as "the tiebreak", it was frequently repeated on TV in later years during rain delays when there was no live play. Borg and McEnroe were polar opposites temperamentally and in their playing styles and yet there was a form of respect between them - McEnroe very rarely behaved badly according to his "Superbrat" reputation during matches with Borg, unlike with other players. This was a fascinating look back at a particular era of the sport which felt like a clash of two different generations (though Borg was only 3 years older). Borg's sudden departure from the tennis scene aged only 25 in 1981 after losing the US Open final to McEnroe, having lost his Wimbledon title to the American earlier that summer, was a shock then, and still comes across as such now. How differently these things were handled in an era long before the internet and social media. ( )
