his highest ever season in terms of prize money. Clarke earned over €2.7 million for the year. 2001–03: Continued success and second WGC win The 2001 season saw Clarke finish one place lower on the Order of Merit in 3rd place, although he did manage some notable results on tour during this season. Clarke added to his list of European Tour wins at the Smurfit European Open, which he won by three strokes at The K Club. A couple of weeks later, Clarke produced another fine performance at The Open Championship at Royal Lytham & St Annes, finishing in a tie for 3rd place, four strokes behind the eventual winner David Duval. Clarke then had another notable 3rd-place finish at the WGC-NEC Invitational, earning in excess of €400,000. In 2002, Clarke played on both the European Tour and the PGA Tour. In the buildup to the Masters, Clarke played the Shell Houston Open and finished second behind runaway winner Vijay Singh. He then played on the European Tour in the summer and won his ninth career title at the Compass Group English Open, becoming the first man to win the tournament three times. In the 2003 WGC-Accenture Match Play Championship, Clarke lost to Peter Lonard at the quarter-final stage. However, Clarke did not have to wait much longer for more WGC success though, when he won his second WGC event at the WGC-NEC Invitational at Firestone Country Club in Akron, Ohio. He finished four strokes ahead of Jonathan Kaye. Clarke's run of success throughout 2001–2003 saw him miss only three cuts on the European Tour in three years and he finished 2nd on the European Order of Merit for the third time in his career. 2004: First winless season in seven years Clarke continued his run of good form at the WGC-Accenture Match Play Championship in 2004, when he finished third. He lost to Davis Love III in the semi-final on the 21st hole, but beat Stephen Leaney 2-up in the resulting 3rd place playoff match. Clarke also had a good finish at the WGC-American Express Championship, finishing in a tie for 4th place. Despite winning over $2 million in prize money, Clarke did not win an event during the 2004 season on either tour and this was the first time this had happened since 1997. 2005–2007: Loss of form and slump Clarke played the 2005 season half and half
