He was the first man since 1886 to contest six consecutive Wimbledon finals, a record surpassed by Roger Federer's seven consecutive finals (2003–09).
He is the only man to achieve the Channel Slam three times.
1956
Björn Rune Borg (born 6 June 1956) is a Swedish former world No. 1 tennis player.
Björn Borg was born in Stockholm, Sweden, on 6 June 1956, the only child of Rune (1932–2008), an electrician, and Margaretha Borg (b. 1934).
He grew up in nearby Södertälje.
As a child, Borg became fascinated with a golden tennis racket that his father won at a table-tennis tournament.
His father gave him the racket, beginning his tennis career.
A player of great athleticism and endurance, he had a distinctive style and appearance—bowlegged and very fast.
His muscularity allowed him to put heavy topspin on both his forehand and two-handed backhand.
He followed Jimmy Connors in using the two-handed backhand.
By the time he was 13, he was beating the best of Sweden's under-18 players, and Davis Cup captain Lennart Bergelin (who served as Borg's primary coach throughout his professional career) cautioned against anyone trying to change Borg's rough-looking, jerky strokes.
1970
A teenage sensation at the start of his career, Borg experienced unprecedented stardom and consistent success that helped propel the rising popularity of tennis during the 1970s.
1972
At the age of 15, Borg represented Sweden in the 1972 Davis Cup and won his debut singles rubber in five sets against veteran Onny Parun of New Zealand.
Later that year, he won the Wimbledon junior singles title, recovering from a 5–2 deficit in the final set to overcome Britain's Buster Mottram.
Then in December, he won the Orange Bowl Junior Championship for boys 18 and under after a straight-sets victory in the final over Vitas Gerulaitis.
1973
Borg joined the professional circuit in 1973, and reached his first singles final in April at the Monte Carlo Open, which he lost to Ilie Năstase.
He was unseeded at his first French Open and reached the fourth round where he lost in four sets to eighth-seeded Adriano Panatta.
Borg was seeded sixth at his first Wimbledon Championships, in large part due to a boycott by the ATP, and reached the quarterfinal, where he was defeated in a five-set match by Roger Taylor.
In the second half of 1973, he was runner-up in San Francisco, Stockholm and Buenos Aires and finished the year ranked No. 18.
Borg made his only appearance at the Australian Open at the age of 17, and reached the third round, where he lost in straight sets to eventual finalist Phil Dent.
In January, he won his first career singles title at the New Zealand Open, followed by titles in London and São Paulo in February and March respectively.
1974
Between 1974 and 1981, he became the first man in the Open Era to win 11 Grand Slam singles titles with six at the French Open and five consecutively at Wimbledon.
Just before his 18th birthday in June 1974, Borg won his first top-level singles title at the Italian Open, defeating defending champion and top-seeded Ilie Năstase in the final and becoming its youngest winner.
Two weeks later, he won the singles title at the French Open, his first Grand Slam tournament title, defeating Manuel Orantes in the final in five sets.
Barely 18, Borg was the youngest-ever male French Open champion up to that point.
1975
In early 1975, Borg defeated Rod Laver, then 36 years old, in a semifinal of the World Championship Tennis (WCT) finals in Dallas, Texas, in five sets.
1976
He was ATP Player of the Year from 1976 to 1980, and was the year-end world No. 1 in the ATP rankings in 1979 and 1980 and ITF World Champion from 1978 to 1980.
Borg is the only Swede, male or female, to win over 10 majors.
1978
Borg won four consecutive French Open titles (1978–81) and is 6–0 in French Open finals.
Borg contested the French Open, Wimbledon and US Open finals in the same year three times (1978, 1980–81).
He won three major titles without dropping a set during those tournaments.
However, he never won the US Open despite four runner-up finishes.
Borg also won three year-end championships and 16 Grand Prix Super Series titles.
Overall, he set numerous records that still stand.
1979
As a result, the professional tour became more lucrative, and in 1979, Borg became the first player to earn more than US$1 million in prize money in a single season.
1980
His rivalry with John McEnroe is considered one of the best in the sport's history, and their meeting in the 1980 Wimbledon final is considered one of the greatest matches ever played.
1981
Borg unexpectedly retired from tennis in 1981, at the age of 25.
1991
He made a brief and unsuccessful comeback in 1991.
Borg is widely considered one of the all-time greats of the sport.
He was ranked by Tennis magazine as the sixth-greatest male player of the Open Era.
