John McEnroe, German-American tennis player and sportscaster
John Patrick McEnroe Jr. (born February 16, 1959), nicknamed Johnny Mac, is an American former professional tennis player. He was known for his shot-making and volleying skills, in addition to confrontational on-court behavior that 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 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 won seven Grand Slam singles titles (four at the US Open and three at Wimbledon), nine Grand Slam men's doubles titles (five at Wimbledon and four at the US Open), and one Grand Slam mixed doubles title (at the French Open). 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 which ended in 1989. Since 2000, there has been only one year-end men's singles event, the ATP Finals (the new name for the Masters Grand Prix). He was named the ATP Player of the Year and the ITF World Champion three times each: 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. He also works as a television commentator during majors tournaments.
