John McEnroe is a former world number one American professional tennis player. Distinguished for his dominant personality as well as his fantastic performance in the tennis court, he is considered by many as one of the greatest players in the game’s history. A holder of seventeen ‘Grand Slam’ titles including seven singles, nine men's doubles and one mixed doubles, McEnroe is reputed for his volleying skills and shot-making finesse. He bagged 19 ‘Grand Prix Super Series’ titles in his career and holds a record of winning eight year-end championships. Throughout his career he won 77 ATP-listed singles titles and 78 doubles titles and had an amazing record of winning 856 singles. The best singles season win rate of ‘open era’ was match record of 82-3 that he achieved in 1984. He became both the ITF World Champion for Men's singles and also the ATP player of the year thrice in his career in 1981, 1983 and 1984. He captained the US team for ‘Davis Cup’ and also remained a player of US ‘Davis Cup’ winning team for five times. However his on-court tirade hurled on ball boys, chair umpires and line judges and confrontational behavior became a common phenomenon which often created conflict with tennis authorities. In 1999 he was enlisted in the ‘International Tennis Hall of Fame’. Post retirement from professional tennis he featured as himself in many television programs and movies and became TV commentator and host of a game and a chat show.
