2004 Grand Prix (snooker)

The 2004 Totesport Grand Prix was the 2004 edition of the Grand Prix snooker tournament and was held from 2 to 10 October 2004 at the Guild Hall in Preston, England. World number one Ronnie O'Sullivan won the tournament defeating Ian McCulloch by nine frames to five (9–5) in the final. In the semi-finals O'Sullivan defeated Paul Hunter 6–3 and McCulloch beat Michael Judge 6–1. Mark Williams, who won the same event under the name LG Cup the year before, lost in the first round. John Higgins made the highest break with a 147. The 64-man tournament was the first of eight WPBSA ranking events in the 2004/2005 snooker season and the next event following last season's World Championship, which was won by O'Sullivan. It preceded the second ranking event of the season, the British Open.

The tournament was created as the Professional Players Tournament in 1982 by the snooker governing body, the World Professional Billiards and Snooker Association (WPBSA), to provide another ranking event. It was renamed the Grand Prix for the 1984 event until 2001, when it was called the LG Cup, before reverting to the Grand Prix this year. The tournament was the first of eight WPBSA ranking events in the 2004/2005 snooker season and the next event following last season's World Championship, which was won by Ronnie O'Sullivan, now a two-time world champion and the world number one. Mark Williams won the same event under the name LG Cup last year. The tournament preceded the second ranking event of the season, the British Open. Sponsored by totesport for the first time after signing a one-year contract announced on the day before the event started, it had a prize fund of £400,000 and was broadcast on the BBC and Eurosport.
