James Scott Connors, known universally as Jimmy Connors, is an American former world No. 1 tennis player. He held the top Association of Tennis Professionals (ATP) ranking for a then-record 160 consecutive weeks from 1974 to 1977 and a career total of 268 weeks. By virtue of his long and prolific career, Connors still holds three prominent Open Era men's singles records: 109 titles, 1,557 matches played, and 1,274 match wins. His titles include eight major singles titles and three year-end championships. In 1974, he became the second man in the Open Era to win three major titles in a calendar year, and was not permitted to participate in the fourth, the French Open. Connors finished year end number one in the ATP rankings from 1974 to 1978. In 1982, he won both Wimbledon and the US Open and was ATP Player of the Year and ITF World Champion. He retired in 1996 at the age of 43.
