John Patrick McEnroe, Jr. (born February 16, 1959) is a former world no. 1 professional tennis player from the United States. During his career, he won seven Grand Slam singles titles (three at Wimbledon and four at the US Open), nine Grand Slam men’s doubles titles, and one Grand Slam mixed doubles title. McEnroe also won a record eight season ending championships, comprising five WCT Finals titles and three Masters Grand Prix titles from twelve final appearances at these two events, a record he shares with Ivan Lendl. He posted the best single season win-loss record in the Open Era in 1984 at 96.47% (82/3). In addition he won 19 Championship Series top tier events of the Grand Prix Tour that were the precursors to the current Masters 1000.
He is best remembered for his shot-making artistry and superb volleying; for his famous rivalries with Björn Borg, Jimmy Connors and Ivan Lendl; for his confrontational on-court behavior which frequently landed him in trouble with umpires and tennis authorities; and for the catchphrase “You cannot be serious!” directed toward an umpire during a match at Wimbledon in 1981. He was inducted into the International Tennis Hall of Fame in 1999, and is regarded as one of the greatest tennis players of all time.
McEnroe is the older brother of Patrick McEnroe, who is also a former professional tennis player and the former Captain of the United States Davis Cup team, a position in which John served previously. They also both are now often commentators for Grand Slam tennis television coverage in the United States, and John McEnroe is also a commentator on Wimbledon for the BBC.
McEnroe was born in Wiesbaden, West Germany, to Kay (née Tresham) and John Patrick McEnroe, Sr. His father, who is of Irish descent, was at the time stationed with the United States Air Force. In 1960, the family moved to the New York City area, where McEnroe’s father worked daytime as an advertising agent while attending Fordham Law School by night. He has two younger brothers: Mark (born 1964), and former professional tennis player Patrick (born 1966).
McEnroe grew up in Douglaston, Queens. He started playing tennis when he was eight years old at the nearby Douglaston Club with his brothers. When he was nine, his parents enrolled him in the Eastern Lawn Tennis Association, and he soon started playing regional tournaments. He then began competing in national juniors tournaments, and at twelve—when he was ranked seven in his age group—he joined the Port Washington Tennis Academy, Long Island, New York. McEnroe attended Trinity School and graduated in 1977.
