What is the Grand Slam?
The term grand slam is used in a number of sports but is perhaps best known as a piece of tennis terminology. The grand slam events in tennis are the Australian Open, the French Open, the US Open and Wimbledon. These are the most prestigious events and the most difficult to win, and it is this which makes the achievement of a grand slam – holding all four titles at one time – so coveted and rare.
How is a Grand Slam Used in Sports Betting?
Although other sports offer grand slams of their own, most sports betting takes place around the likelihood of tennis players winning individual grand slam titles, and of the less likely possibility of one player holding all of the titles at once. In the history of tennis, the grand slam has been achieved only 6 times, by Don Budge, Maureen Connolly, Rod Laver (twice), Margaret Court and Steffi Graf. In addition to this, 7 players have achieve the feat of winning all four major titles in a row, although not necessarily in the same season, and these are Budge, Connolly, Laver (twice), Court, Graf (twice), Martina Navratilova and Williams. The difficulty of achieving a genuine Grand Slam, or of winning four titles in a row, is such that bookmakers are likely to offer very good odds at the start of a tennis season, becoming shorter as the season progresses and 1 player picks up 1, 2 or more titles. A bet on a grand slam could be placed as a single bet, on the overall result, or as an accumulator based on the results of the four individual tournaments. When placing a Grand Slam bet it is vital to be clear with the bookmaker whether the Grand slam in question will take place over a calendar year, or just across four consecutive tournaments.
Other sports which offer the opportunity to bet on a grand slam include golf, in which the grand slam includes the four major annual tournaments and Rugby Union, whereby the Grand Slam consists of one international team beating all others during the Six Nations Championship.
