McIlroy Remains World No.1

The past week's golfing action has not brought any significant changes to the top of the world rankings.

Despite his successful defence of the Indonesian Masters title, Lee Westwood was not able to improve on his third place, with Rory McIlroy remaining on top and Luke Donald still holding strong in second.

Bubba Watson remains fourth after his Masters triumph, with Hunter Mahan following in fifth.

South African Branden Grace, meanwhile, is now up to 66th in the world following his third victory of the season at the Volvo China Open. The European Tour qualifying school graduate began the season in 271st.

Former Open champion Ben Curtis won the Valero Texas Open and moves from 285th to 156th.
