John McEnroe

John Patrick McEnroe, Jr. (born February 16, 1959 in Wiesbaden, Germany) is a former World No. 1 professional tennis player from the United States. Scott Riley, writing for The Sports Network, recognized him as one of the greatest tennis players of all time. During his career, he won seven Grand Slam singles titles – three at Wimbledon and four at the U.S. Open. He also won nine Grand Slam men's doubles titles and one Grand Slam mixed doubles title. He is remembered for his shot-making artistry and supreme volleying; for his matches against Björn Borg; for his fiery on-court temperament, 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.

After a 12-year absence from the professional tour, McEnroe returned to top-level doubles competition in 2006 and became the oldest male player to win a top-level title in 30 years at San Jose.
