John McEnroe
Updated: Wikipedia source
John Patrick McEnroe Jr. (born February 16, 1959) is an American former professional tennis player. He was ranked as the world No. 1 in men's singles by the Association of Tennis Professionals (ATP) for 170 weeks, and as world No. 1 in men's doubles for 269 weeks (third-most of all time). He is one of two male players (alongside Stefan Edberg) to have held both No. 1 rankings, and the only one to hold both simultaneously. McEnroe was best known during his playing career 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 won an Open Era record 155 career titles: 77 in singles, 77 in doubles and 1 in mixed doubles. This includes seven singles majors (four at the US Open and three at Wimbledon), nine men's doubles majors, and one mixed doubles major. McEnroe is the only male player to win more than 70 titles in both singles and doubles. His singles match record of 82–3 in 1984 remains the best single-season win rate of the Open Era. McEnroe also excelled at the year-end tournaments, winning eight singles and seven doubles titles, both of which are records. Three of his winning singles year-end championships were at the Masters Grand Prix (the ATP year-end event) and five were at the World Championship Tennis (WCT) Finals, an event that ended in 1989. He was named the ATP Player of the Year and the ITF World Champion three times each: in 1981, 1983 and 1984. McEnroe contributed to five Davis Cup titles for the U.S. and later was team captain. He has stayed active in retirement, often competing in senior events on the ATP Champions Tour, where he has won 25 titles. He also works as a television commentator during the majors.
