64-man WGC-Accenture Match Play Championship, which selected its field on the basis of the World Rankings, was a blow to the prestige of the older event, whose exhibition aspects, with a small invited field, were emphasised by contrast. In 2003, the tournament was given a major overhaul. Greatly increased sponsorship was secured from the largest British based bank, HSBC, and the winner's prize was increased to £1 million, which was then easily the largest in world golf (although the Nedbank Golf Challenge had had a $2 million first prize from 2000–02). In 2004, the championship became an official money European Tour event - not, however, the actual prize money, as the first prize was far higher than for the other events on the tour, but scaled-down amounts intended to be more proportionate. The field was increased to 16 players, all of whom needed to play eight rounds of golf to win, to eliminate the advantage previously given to seeds. A qualifying system, based primarily on performances in the four majors, replaced the invitations of the past. World ranking points were allocated to the event for the first time since 1999. In recent years, Americans have tended to decline their invitations. In 2005, no Americans took part at all, and with stalwart Ernie Els injured and Vijay Singh and Sergio García also absent, the field was one of the weakest seen at the event, with just one player from the world top ten. The 2006 event had a considerably stronger field with six of the world's top ten players headed by the world's top two ranked players Tiger Woods and Jim Furyk. But in January 2007 HSBC activated a break clause in its ten-year contract and withdrew from sponsorship after the 2007 event. After HSBC withdrew its sponsorship in 2007, the tournament was given another major overhaul. After a break in 2008, the tournament returned in 2009 with Volvo as the new title sponsor. The event moved from Wentworth to the Finca Cortesín Golf Club near Málaga in Spain. The format switched to an opening round robin, with 16 players divided into four groups and the winners advancing to the 36-hole semi-finals. The qualifying criteria were also changed to include certain players based on their nationality. The total prize money for 2009 was €3,250,000, with €750,000 of that going to the winner. After another break in 2010, the tournament returned in
