Björn Rune Borg ; born 6 June 1956) is a former World No. 1 tennis player from Sweden; he won a record five consecutive Wimbledon singles titles (an all-time record he holds with Roger Federer) and four consecutive French Open singles titles (an all-time record he holds with Rafael Nadal), and is considered to be one of the greatest tennis players of all time.
During his relatively brief pro career, Borg won 41 percent of the Grand Slam singles tournaments he entered (11 of 27) and 89.8 percent of the Grand Slam singles matches he played. Both are open era male records for an entire career. In addition, Borg's six French Open singles titles are an all-time record. He is the only player in the open era to win both Wimbledon and the French Open in the same year more than once, winning both for three consecutive years.
