John McEnroe
John Patrick McEnroe Jr. is an American former professional tennis player and musician. He was known for his shot-making and volleying skills, his rivalries with Bjorn Borg and Jimmy Connors, and his confrontational on-court behavior, which frequently landed him in trouble with umpires and tennis authorities. McEnroe attained the world No. 1 ranking in both singles and doubles, finishing his career with 77 singles titles on the ATP Tour and 78 doubles titles; this remains the highest men's combined total of the Open Era. He thus remains the only male player to win more than 70 titles in both the men's singles and the men's doubles categories. He also won 25 singles titles on the ATP Champions tour. He won seven Grand Slam singles titles, nine Grand Slam men's doubles titles, and one Grand Slam mixed doubles title. His singles match record of 82–3 in 1984 remains the best single season win rate of the Open Era.
