1972–73 – Davis Cup debut and first year on the tour At the age of 15, Borg represented Sweden in the 1972
Davis Cup and won his debut singles rubber in five sets against
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. 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.
1974 – First French Open title at
Rotterdam Open in 1975 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 the 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. 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. At Wimbledon, Borg lost in the third round to Ismael El Shafei in straight sets in a match in which "Borg quit trying mid-way through the second set". At the US Open, Borg lost in the second round to Vijay Amritraj in five sets which was "one of the memorable matches on the famed center court- a duel of strategy and stroke making".
1975 – Retained French Open title at the
French Open final in 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. Borg subsequently lost to
Arthur Ashe in the final. Borg retained his French Open title in
1975, beating
Guillermo Vilas in the final in straight sets. Borg then reached the Wimbledon quarterfinals, where he lost to eventual champion Ashe. Borg did not lose another match at Wimbledon until 1981. Borg lost in the semi-finals of the US Open on clay in straight sets to Connors. Connors' "tremendous power when he found himself behind, blunted the 19-year-old Swede's topspin and balloon ball hitting". Borg won two singles and one doubles rubber in the 1975 Davis Cup final, as Sweden beat
Czechoslovakia 3–2. With these singles wins, Borg had won 19 consecutive Davis Cup singles rubbers since 1973. That was already a record at the time. However, Borg never lost another Davis Cup singles rubber, and, by the end of his career, he had stretched that winning streak to 33.
1976 – First Wimbledon title In early 1976, Borg won the
World Championship Tennis year-end
WCT Finals in
Dallas, Texas, with a four-set victory over
Guillermo Vilas in the final. At the 1976 French Open, Borg lost to the Italian
Adriano Panatta, who remains the only player to defeat Borg at this tournament. Panatta did it twice: in the fourth round in 1973, and in the 1976 quarterfinals. Borg won Wimbledon in
1976 without losing a set, defeating the favored
Ilie Năstase in the final. Borg became the youngest male Wimbledon singles champion since Sidney Wood in 1931 at 20 years and 1 month (a record subsequently broken by
Boris Becker, who won Wimbledon aged 17 in 1985). Năstase later said, "We're playing tennis and he's playing something else." Borg also reached the final of the
1976 U.S. Open, which was then being played on clay courts. Borg lost in four sets to world no. 1
Jimmy Connors. Borg was awarded the ATP Player of the Year award and ranked world No. 1 by
Tennis Magazine (France).
1977 – Second Wimbledon title and world No.1 ranking In February 1977
World Championship Tennis (WCT) sued Borg and his management company
IMG claiming that Borg had committed a breach of contract by electing to participate in the competing
1977 Grand Prix circuit instead of the
WCT circuit. Borg eventually played, and won, a single WCT event, the Monte Carlo WCT. An out-of-court settlement was reached whereby Borg committed to play six or eight WCT events in 1978 which were then part of the
Grand Prix circuit. Borg skipped the French Open in 1977 because he was under contract with
WTT, but he repeated his Wimbledon triumph, although this time he was pushed much harder. He defeated his good friend
Vitas Gerulaitis in a semifinal in five sets. His match with Gerulaitis was deemed by Wimbledon itself as "probably the greatest gentlemen's singles match played at Wimbledon". In the
1977 final Borg was pushed to five sets for the third time in the tournament, this time by Connors. The win propelled Borg to the No. 1 ranking in the ATP point system, albeit for just one week in August. Before the 1977 US Open, Borg aggravated a shoulder injury while waterskiing with Vitas Gerulaitis. This injury ultimately forced him to retire from the Open during a Round of 16 match vs
Dick Stockton. Borg was rated number one for 1977 by
Tennis Magazine (France),
Tennis Magazine (U.S.), Barry Lorge, Lance Tingay, Rino Tommasi, Judith Elian and Rod Laver. Borg was also named "ATP Player of the Year". Through 1977, he had never lost to a player younger than himself.
1978 – French and Wimbledon titles Borg was at the height of his career from 1978 through 1980, completing the French Open-Wimbledon double all three years. In
1978, Borg won the French Open with a win over Vilas in the final. Borg did not drop a set during the tournament, a feat only he, Năstase (in 1973), and
Rafael Nadal (in 2008, 2010, 2017, and 2020) have accomplished at the French Open during the open era. In round one of
Wimbledon Borg was 2 sets to 1 down, 3–1 down, and 30–40 on his serve, one point from going a double break down against the big serving 6 feet 7 inches tall
Victor Amaya. Borg came back to win in five sets. Borg beat Connors in straight sets in the final. At the
1978 US Open, now held on hard courts in Flushing Meadows, New York, he lost the final in straight sets to Connors. Borg was suffering from a bad blister on his thumb that required pre-match injections. That autumn, Borg faced
John McEnroe for the first time in a semifinal of the Stockholm Open, and lost. Borg was named ATP Player of the Year and was the first ITF World Champion.
1979 – French and Wimbledon titles and year-end No. 1 ranking Borg lost to McEnroe again in four sets in the final of the 1979 WCT Finals, but was now overtaking Connors for the top ranking. Borg established himself in the top spot with his fourth French Open singles title and fourth straight Wimbledon singles title, defeating Connors in a straight-set semifinal at the latter tournament. At the
1979 French Open, Borg defeated big-serving
Víctor Pecci in a four-set final. In the
1979 Wimbledon final Borg came from behind to overcome an even bigger server,
Roscoe Tanner in five sets, admitting afterwards that "at the end of the match I have never been so nervous in my whole life". Borg was upset by Tanner at the US Open, in a four-set quarterfinal played under lights. At the season-ending
Masters tournament in January 1980, Borg survived a close semifinal against McEnroe. He then beat Gerulaitis in straight sets, winning his first Masters and first title in New York. Borg finished the year at No. 1 in the ATP Point rankings and was considered the No. 1 player in the world by most authorities. Borg then won his fifth consecutive Wimbledon singles title on 5 July, defeating McEnroe in
a five-set final, often cited as the best Wimbledon final ever played. Having lost the opening set to an all-out McEnroe assault, Borg took the next two sets and had two championship points at 5–4 in the fourth; however, McEnroe averted disaster. With the score 6–6, there took place Wimbledon's most memorable tiebreaker – in which McEnroe saved five championship points, and Borg six set points, before McEnroe won 18–16, taking the fourth set and levelling the match. In
September 1980, Borg reached the final of the U.S. Open for the third time, losing to McEnroe in five sets in a match that cemented what had become the greatest contemporary rivalry, albeit short-lived, in men's tennis. He defeated McEnroe in the final of the 1980 Stockholm Open, and faced him one more time that year, in the round-robin portion of the year-end Masters, actually played in January 1981. With 19,103 fans in attendance, Borg won a deciding third-set tie-break for the second year in a row. Borg defeated
Ivan Lendl in the final for his second Masters title. Nevertheless, Borg's announcement in January 1983 that he was retiring from the game at the age of 26 was a shock to the tennis world. McEnroe tried unsuccessfully to persuade Borg to continue. He did, however, play Monte Carlo again in March 1983, reaching the second round, and Stuttgart in July 1984, losing to
Henri Leconte on both occasions. Upon retirement, Borg had three residences: a penthouse in Monte Carlo, not far from his
pro shop; a mansion on Long Island, New York; and a small island off the Swedish coast. Borg later bounced back as the owner of the
Björn Borg fashion label. In Sweden, his label has become very successful, second only to
Calvin Klein.
1991–93: Attempted comeback In 1991–1993, Borg attempted a comeback on the men's professional tennis tour, coached by Welsh karate expert Ron Thatcher. Before his 1991 return, Borg grew his hair out as it had been during his previous professional tennis career, and he returned to using a wooden racket; he had kept his hair short and used modern graphite rackets in exhibitions he played during the late 1980s. Borg, however, failed to win a single match. He faced
Jordi Arrese in his first match back, again at Monte Carlo, but without practising or playing any exhibition matches, and lost in two sets. In his first nine matches, played in 1991 and 1992, Borg failed to win a single set. He fared slightly better in 1993, taking a set off his opponent in each of the three matches he played. On 9 November 1993 at the
Kremlin Cup in Moscow in what turned out to be his final tour match, he came closest to getting a win but failed to convert a match point and eventually lost to second seed and world No. 17
Alexander Volkov 6–4, 3–6, 6–7(7–9). In 1992, Borg, aged 35, using a graphite racket, defeated
John Lloyd, 37, at the Inglewood Forum Tennis Challenge. Borg later joined the Champions tour, using modern rackets. ==Playing style==
