Luke Donald tops golf world rankings

England's Luke Donald is world number one for the second straight week leading a European clean sweep of the top three places.
Donald took over from compatriot Lee Westwood last week following his playoff win over the same player at the PGA Championship at Wentworth.
Steve Stricker is up to fourth and is the top American in the rankings following his win Sunday in the Memorial at Dublin, Ohio.
Tiger Woods slipped a further couple of places and is now 15th ahead of his scheduled return to action at the US Open in Washington DC on June 16.
