The Australian Open is an annual tennis tournament created in 1905 and (since 1988) played on outdoor hardcourts at Melbourne Park in Melbourne, Australia. The Australian Open is played over a two-week period beginning in mid-January and has been chronologically the first of the four Grand Slam tournaments each year since 1987. The event was not held from 1916 to 1918 because of World War I, from 1941 to 1945 because of World War II and in 1986. The timing of the Australian Open has changed several times. In 1977, the date of the final moved from January to December, which resulted in having two Australian Opens in 1977; there was a January edition and a December edition that year. The originally planned December 1986 edition was moved forward to January 1987, resulting in no Australian Open in 1986. The Australian Open was an Open Era event for the first time in 1969. One year previously in 1968 the French Open, Wimbledon and the US Open were Open Era events for the first time. (Full article...)

A clay court is one of the types of tennis court on which the sport of tennis is played. Clay courts are built on a foundation of crushed stone, brick, shale, and other aggregate, with a thin layer of fine clay particles on top. Clay courts are more common in Continental Europe and Latin America than in North America, Asia-Pacific or Britain. The only Grand Slam tournament that uses clay courts is the French Open.

Clay courts come in the more common red clay (known in France as terre battue), which is actually crushed brick, and the slightly harder green clay, which is actually crushed metabasalt. Although slightly less expensive to construct than other types of tennis courts, clay requires much maintenance: the surface must be watered and rolled regularly to preserve texture and flatness, and brushed carefully before each game.

The Borg–McEnroe rivalry was a tennis rivalry between Björn Borg and John McEnroe, who met 14 times on the regular tour and 22 times in total between November 1978 and April 1981. Their head-to-head was even at 7–7. Their on-court rivalry was highlighted by their contrasting temperaments and playing styles: the Swede Borg was known for his cool and emotionless demeanor on court, while the American McEnroe was famed for his court-side tantrums. As a result, their rivalry was described as "Fire and Ice". They were tied in their five-set matches at 1–1.

In 1980, McEnroe reached the singles final at Wimbledon for the first time, where he faced Borg, who was aiming for an Open Era record fifth consecutive Wimbledon title. At the start of the final McEnroe was booed by the crowd as he entered Centre Court following his heated exchanges with officials during his semi-final clash with Jimmy Connors. In a fourth set tie-breaker that lasted 20 minutes, McEnroe saved five match points (seven altogether in that set) and eventually won 18–16. However, he was unable to break Borg's serve in the fifth set and Borg went on to win 8–6. This match is widely considered one of the best tennis matches ever played. McEnroe defeated Borg at the US Open final the same year in five sets. (Full article...)

Although Becker led their overall head-to-head 25–10 and won all three of their Davis Cup matches, Edberg won three of their four meetings in Grand Slams. Edberg and Becker also reached the championship match of the 1989 World Tour Finals, which Edberg won in four sets. Edberg led their five-set matches at 2–1.

The most defining aspect of their rivalry was the three successive Wimbledon finals that they played. In the 1988 meeting, Becker was the huge favorite, and stormed to the first set 6–4. The second set was to be the most memorable, when in a fit of courage and tennis acumen Edberg won a tight set in a tiebreaker 7–2. Edberg went on to win the next two sets 6–4, 6–2 to win his first Wimbledon title and deny Becker a third title in four years. In the 1989 meeting, Becker, having lost to Edberg a month earlier in the French Open semifinals, raced to win the first set 6–0. The second set was closer, but won in a tiebreak by Becker 7–1 after saving 3 set points (Edberg led 6-5 40-0 and service). Becker went on to win the third set 6–4. This was Becker's third Wimbledon title, which would be his last Wimbledon crown. In the 1990 meeting, Edberg won the first two sets 6–2, 6–2. However, Becker rallied to win the next two sets 6–3, 6–3. Becker broke Edberg early in the fifth set, setting up the possibility of being the first Wimbledon champion since Henri Cochet in 1927 to win the final after losing the first two sets. Yet, this was not to be as Edberg regained the break and then broke Becker in the ninth game of the set with a topspin lob winner, eventually serving it out for a second Wimbledon championship.

The Grand Slam in tennis is the achievement of winning all four major championships in one discipline in a calendar year. In doubles, a Grand Slam may be achieved as a team or as an individual with different partners. Winning all four major championships consecutively but not within the same calendar year is referred to as a "non-calendar-year Grand Slam", while winning the four majors at any point during the course of a career is known as a "Career Grand Slam".

The term Grand Slam is also attributed to the Grand Slam tournaments, referred to as Majors, and they are the world's four most important annual professional tennis tournaments. They offer the most ranking points, prize money, public and media attention, the greatest strength and size of the field and, in recent years, the longest matches for men (best of five sets, best of three for the women). The tournaments are overseen by the International Tennis Federation (ITF), rather than the separate men's and women's tour organizing bodies, the Association of Tennis Professionals (ATP) and Women's Tennis Association (WTA), but both the ATP and WTA award ranking points based on players' performances in them.
