Björn Rune Borg (Swedish pronunciation: [ˈbjœːɳ ˈbɔrj] (About this soundlisten); born 6 June 1956) is a Swedish former world No. 1 tennis player. Between 1974 and 1981, he became the first man in the Open Era to win 11 Grand Slam singles titles (six at the French Open and five consecutively at Wimbledon), but he never won the US Open despite four finals appearances. He is the first male player to win five Wimbledon titles in the Open Era.
Borg won four consecutive French Open titles (1978–81) and is 6–0 in French Open finals, the fourth-best record at a Grand Slam behind Pete Sampras (7-0 at Wimbledon finals), Novak Djokovic (9-0 at Australian Open finals) and Rafael Nadal (13-0 at French Open finals). He is one of two male players, along with Roger Federer, to appear in French Open and Wimbledon finals for four consecutive years (1978–81) and the only man to win both of them in three consecutive years (1978–80). He is the first male player to appear in French Open, Wimbledon and US Open finals in the same year three times (1978, 1980–81), a record surpassed by Federer who achieved the same in four consecutive years (2006–09). He won three major titles without dropping a set in the entire tournament.
He also won three year-end championships and 16 Grand Prix Super Series titles. Overall, he set numerous records that still stand. Borg was the first player to win six French Open singles titles. He is considered to have been the No. 1 player in the world for 1977,[1][2][3][4][5] 1978,[6][3][7] 1979[6][3][7] and 1980.[3][6][7]
A teenage sensation at the start of his career, Borg's unprecedented stardom and consistent success helped propel the rising popularity of tennis during the 1970s.[8] As a result, the professional tour became more lucrative, and in 1979, he was the first player to earn more than one million dollars in prize money in a single season. He also made millions in endorsements throughout his career. However, the constant attention and pressure eventually caused burnout and his early retirement at the age of 26.[
