Taylor's other losses to Part came in the 2003 Las Vegas Desert Classic (13–10 in the semi-final), the 2004 UK Open (8–6 in the quarter final) and at the 2005 World Matchplay (16–11 in the quarter final). Part won the 2008 PDC World Championship and became the second player after Taylor to have won the tournament more than once. Taylor and Part met in competition on at least 37 occasions, with Taylor winning 31 and Part winning 6. While Taylor was racking up World titles in the PDC, Raymond van Barneveld was amassing four in the BDO. Darts was denied a great rivalry as the two best players were unable to compete against each other regularly due to the split in the game. Van Barneveld switched to the PDC in 2006. Their first clash came in the 2006 Premier League Darts tournament and ended in a 7–7 draw. The return match went in Taylor's favour. Barneveld's first PDC win over Taylor came at the 2006 UK Open with an 11–10 quarter-final success, which he followed up with success in the semi-finals of the Las Vegas Desert Classic, winning by four sets to three. Taylor later defeated van Barneveld by three sets to one in the World Grand Prix. They then met in the final of the 2007 PDC World Championship at the Circus Tavern. The match has been described as the greatest game in the history of darts. Despite being up three sets to nil at one point, Taylor was defeated by van Barneveld seven sets to six in a sudden-death leg. Taylor responded to his loss by defeating van Barneveld on two occasions in the 2007 Premier League Darts and beating him in the final of the inaugural US Open. Van Barneveld later defeated Taylor in the quarter-finals of the UK Open by 11 legs to four. Taylor lost his top spot in the PDC World Rankings to van Barneveld in January 2008, but regained it in June. In major PDC tournaments in 2008, Taylor defeated van Barneveld twice in the Premier League, lost by 10 legs to nine in the quarter-finals of the UK Open, but won the World Grand Prix against his rival by six sets to two. The rivalry continued into 2009 with the two meeting in the World Championship final for a second time, with Taylor winning 7–1 with a 110.94 three-dart average. The two then met in the 2010 World Matchplay final; Taylor won 18–12, averaging more than 105, which was higher than van Barneveld's 100.11 average.
