PGA European Tour

At the start of 2006 five of the top 10 players in the Official World Golf Ranking were full members of the European Tour, namely Ernie Els, Retief Goosen, Sergio García, Adam Scott and Colin Montgomerie. Two years later, at the start of 2008, the number of full European Tour members in the top 10 remained at five, namely Els, Justin Rose, Scott, Pádraig Harrington, and Vijay Singh. At the start of 2009, that number increased to seven--García, Harrington, Singh, Robert Karlsson, Henrik Stenson, Els, and Lee Westwood. At the start of 2010, that number went back to five, with Westwood, Harrington, and Stenson joined by Paul Casey and Rory McIlroy. Apart from McIlroy, who was only 20 years old at the end of 2009, and longtime European Tour veterans Montgomerie and Karlsson, all of the named golfers are also members of the PGA Tour, and moved to it as their main or joint main tour after playing in Europe first. Singh had largely abandoned the European Tour for the PGA Tour in the late 1990s, but rejoined the European Tour in 2006. 2010 saw much success for European Tour members, including major wins for Graeme McDowell, Louis Oosthuizen and Martin Kaymer, and a victory in the 2010 Ryder Cup. Lee Westwood ended the year as world number one. As of 24 January 2011, the no. 1 and 2 positions in the golf rankings were occupied by Europeans (Westwood and Kaymer), for the first time in 18 years. Westwood, Kaymer, no. 4. McDowell and no 7. McIlroy all see the European Tour as their primary tour.
