On a clear September New York evening in 1981, following a soul crushing loss to John McEnroe in the US Open final for the second consecutive year, Björn Borg disappeared into the night and vanished from the sport. He was only 25. He had accumulated an extraordinary 11 grand slam titles by then, but it left one to wonder how many more championships he could have amassed had he not retired so young. His conqueror that day had a much longer career and played until he was 33. But McEnroe, like Borg, won his last grand slam singles title at 25.
Back in those old days of the first phase of Open tennis (which I’ll date from 1968-1985; most of the top pros didn’t start playing the Australian Open regularly until the mid-1980s), players reached their peaks in their mid-20s and winning majors as one approached 30 was considered unusual.
