Dunlop’s Lee Westwood has become world number one for the first time, ending American Tiger Woods’s 281-week reign at the top of the golf rankings.
German Martin Kaymer needed a top-two finish at Valderrama to become number one himself but ended Sunday’s fourth round well off the lead at seven over.
Kaymer fired a final-round 75 to finish 10 shots behind winner Graeme McDowell.
Westwood, 37, becomes Europe’s first number one golfer since compatriot Nick Faldo achieved the feat in 1994.
