It was the peak of the Fire and Ice rivalry. Tennis legend Björn Borg was chasing a sixth straight Wimbledon title in 1981. Facing his American rival John McEnroe in a repeat of the 1980 final, Borg fell in a four-set epic, and again two months later in the US Open final.
Borg would not play another Grand Slam match again. In a move that shocked the tennis world, he announced his retirement in 1983, at just 26 years old.
