John Patrick McEnroe Jr. (born February 16, 1959) is an American former professional tennis player known for his shot-making and volleying skills, his rivalries with Björn Borg and Jimmy Connors, and his confrontational on-court behavior, which frequently landed him in trouble with umpires and tennis authorities. McEnroe is the only male player since the inception of the ATP rankings in 1973 to simultaneously hold the world No. 1 rankings in both singles and doubles. Only one other player, Stefan Edberg, ever attained No. 1 in both disciplines.
