"If we just prepared it on the points won so far this year Woods would not be in the top 50"

The European Tour's statistics expert Ian Barker defended the World Ranking after Butch Harmon criticized the elevation of Lee Westwood to the top spot.

"If we just prepared it on the points won so far this year Woods would not be in the top 50 and Martin Kaymer would be comfortably the world number one," Barker, the European Tour's director of information services, told Reuters.

"Anyway, Butch may well have his wish on Sunday because Martin will go to number one if he comes second in Valderrama."
