James Scott Connors (born September 2, 1952) is a retired American world No. 1 tennis player, often considered among the greatest in the history of the sport. He held the top 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 (the only man to reach 100), 1535 matches played, and 1256 match wins. His titles include eight majors (five US Open, two Wimbledon, one Australian Open), three year-end championships, and 17 Grand Prix Super Series. In 1974, he became the second man in the Open Era to win three majors in a calendar year, and his total career match win rate remains in the top five of the era.
Connors was known for his fiery competitiveness, acrimonious relationships with a number of peers, and boorish behavior that pandered to the crowd. For these reasons, he has been likened to baseball player Pete Rose, a comparison Connors is proud of.
