Masters champion surges up the world rankings
Although a South African who lives for most of the year in Lake Nona, Florida, Immelman began his professional career from a base in Richmond, England, and has retained his membership of the European Tour. His win in Augusta has shot him straight to the top of the order of merit with 992,958 points.
Graeme McDowell is best of the Irish, fifth with 552,750, followed by Harrington (11th with 419,672), Damien McGrane (18th with 311,088) and Paul McGinley (229,980).
