Clean sweep is a term used when a punter’s bets all come in as winners and none are left out as losers.
It can also be used as a term in multiple sports such as horse racing in which a stable has all of its horses win in a meeting or in football where a team wins all of the competitions it enters.
It is often used in cricket as well and can be used if, for example, Australia beat England 5-0 in the Ashes, they are said to have won by a clean sweep or whitewash.
However, a clean sweep is a rarity in most sports and if betting on it happening, the odds are often quite substantial.
An example of a clean sweep in betting would be backing Manchester United to win the FA Cup, League Cup, Champions League and Premier League title.
Due to the unlikeliness of this occurrence – it has never happened yet by a Premier League team, with United’s treble-winning 1998-99 season seeing them miss out on the League Cup – the odds will reflect this and often be very long and more often than not better placed as an outside bet.
However, there are more winnable clean sweeps, such as backing an international cricket team to win all of the test matches it plays against a nation in a test series as England found out to their detriment when the Australians performed a clean sweep, winning 5-0 during the 2013-14 Ashes series.
Pakistani squash player Jahangir Khan went on a five-year clean sweep of all his opponents winning 555 consecutive matches from 1981 to 1986.
It remains to this day the most matches ever won consecutively by a professional sportsman and is a prime example of how to clean sweep all of your opponents.
