Bjorn Borg's retirement
Never realized Borg faced qualifying for every tourney in 1982 due to his lack of play the prior year. "Borg was an unusual champion in that he never followed the entire world-wide tour. He insisted on taking a four-month vacation, which embroiled him in a dispute with the men's tennis council in 1982. Borg was told he would have to enter the qualifying round for every major event that year because he refused to commit himself to playing the required number of tournaments. As a result, he took the year off and then announced his retirement in 1983, when he was only twenty-seven."
