Golf world rankings

A third-place finish at the Zurich Classic in New Orleans was enough for Luke Donald to reclaim the world number one spot from Rory McIlroy.

The Ulsterman, who held the top spot for two weeks, could supplant Donald once again this week if he does well at the Wells Fargo Championship, a tournament that the Englishman will miss.

The world number one spot has changed hands nine times in the last 18 months, with Tiger Woods, Lee Westwood and Martin Kaymer also holding the position.

American Jason Dufner, who won the Zurich Classic, enters the top 20, while Ernie Els, who lost in a playoff, moves up to 40th which should ensure he plays in the US Open in June.
