The Masters is a professional snooker tournament and the second longest running tournament outside the World Championship and is one of the Triple Crown events. Although not a ranking event, it is regarded as one of the most prestigious tournaments on the circuit. The defending champion is Neil Robertson.

The tournament was held for the first time in 1975 in the West Center Hotel, London, when the top ten players were invited. The event was sponsored by the cigarette company, Benson & Hedges. The final was won by John Spencer, who beat Ray Reardon 9–8 to win £2,000. The following year the event moved to the New London Theatre and in 1979 to the Wembley Conference Centre.

In 1981 the number of players invited to compete was increased to 12, and then increased again to 16 in 1983. From 1984 onwards the top 16 players in the world rankings were automatically invited to the tournament. In 1984 Kirk Stevens became the first player to make a maximum break at the event against Jimmy White in the semi-final. In 1988 Mike Hallett became the first and to date only player to be whitewashed in a Masters final, having lost 0-9 to Steve Davis.Stephen Hendry maintained an unbeaten record in the event, a run which included five successive championship victories, from his first appearance in 1989 until his defeat by Alan McManus in a final-frame decider in the 1994 final. Hallett reached his second final in four years in 1991, but lost 8–9 against Hendry, despite leading 7–0 and 8–2. This defeat effectively ended Hallett's days as a major force in the game.

Ronald Antonio "Ronnie" O'Sullivan (born 5 December 1975) is an English professional snooker player known for his rapid playing style, and is nicknamed "The Rocket". He has been World Champion on four occasions (2001, 2004, 2008 and 2012) and, with career earnings of over £6 million is second after Stephen Hendry on snooker's all-time prize-money list. O'Sullivan has been the world's no. 1 player on five occasions, and has won a total of 24 ranking titles. He is second, again behind Hendry, on the list of players making the most competitive century breaks, with a total of 678. O'Sullivan has compiled 11 maximum breaks in professional competition, a record which he shares with Hendry. He also holds the record for the fastest maximum break, at 5 minutes 20 seconds.

O'Sullivan is considered by many fans, critics and professionals, including fellow multiple-World Championship winners Hendry and Steve Davis, as the most naturally talented player in the history of the game. He has, however, been involved in a number of controversial incidents during his career.

Robert Milkins (born 6 March 1976) is an English professional snooker player from Gloucester. Milkins' highest ever world ranking is 21, and he spent 4 seasons in the top 32, before dropping to #47 for the 2007/2008 season.

He turned professional in 1995, but dropped off the Main Tour when it was reduced in size after the 1996/1997 season, but returned a year later via the UK Tour. After four seasons of solid progress with occasional last-16 runs, he reached the last 16 of the World Snooker Championship in 2002, and the first round in each of the next three years.

He made history in qualifying for the 2006 World Snooker Championship by making a 147 break in his match against Mark Selby. He became only the sixth player to achieve a maximum in the tournament, and the first to do so in qualifying (as a result, he earned £5,000; in the main tournament it would be worth £147,000). He ultimately lost to Selby 4–10, becoming only the second player to lose a World Championship match despite a 147, the other being Ronnie O'Sullivan against Marco Fu in 2003. Milkins also made a maximum break against Xiao Guodong in the fourth qualifying round of the 2012 tournament, and this time he won the match 10–4. He has also been on the wrong end of a 147 in the tournament – Mark Williams completed a 10–1 victory in the first round of the 2005 tournament with a final-frame maximum.

Dominic Dale (born Christopher Dale in Coventry, England on 29 December 1971) is a Welsh professional snooker player and occasional snooker commentator and presenter for the BBC.

Dale won the Welsh Amateur Championship, which allowed him to compete at the World Amateur Championship in Bangkok. Dale reached the final, but lost 9–11 against Noppadon Noppachorn. Dale turned professional for the 1992/1993 season.

He has won two ranking tournaments in his career, the first of which – the Grand Prix in 1997 – he won while ranked number 54 in the world, beating then world number 2 John Higgins 9–6 in the final. It took him a decade to repeat the achievement at the 2007 Shanghai Masters, where he defeated compatriot Ryan Day 10–6 in the final, from 2–6 behind. On his way to the Shanghai final he beat Rory McLeod, Ken Doherty, Adrian Gunnell, Dave Harold and Mark Selby.

Both of his ranking victories were in the season-opening tournaments; he also reached the semi-finals of the season-opening events in 2002 (LG Cup) and 2006 (Northern Ireland Trophy). He also beat Peter Ebdon at the 2008 Malta Cup, despite a bout of stomach cramps and a drinking session the night before the match.

Ryan Day (born 23 March 1980, in Pontycymer, Bridgend, Wales), is a Welsh professional snooker player. He is known as a very solid breakbuilder and is one of only 35 players to have made over a century of centuries.

He was named Young Player of Distinction of the season 2000/2001 by the World Professional Billiards and Snooker Association (WPBSA). He won the 2001 Benson & Hedges Championship. With this win, he qualified for the 2002 Masters, where he defeated Dave Harold, before losing 0–6 to Stephen Hendry. He also won the WPBSA Challenge Tour in the 2001/2002 season and was named WPBSA Newcomer of the Year in 2002. Due to problems with his liver in 2003, his results suffered badly.

In 2004, however, he qualified for the World Snooker Championship and he led John Higgins 9–7 in the first round, becoming the first player to score three centuries in his first Crucible match, but missed a pink in the 17th frame that would have left Higgins needing a snooker to stay in the tournament. Higgins went on to win the frame and the next two for the match. As some consolation, Higgins commented that Day was "going to be a top player for many years to come".
