Sotogrande: Martin Kaymer produced his best round of the week at the Andalucia Masters on Saturday but the young German`s chances of claiming the world number one spot look slim.
A bogey on Valderrama`s final hole gave him a third-round 70 and a three-over-par aggregate of 216, leaving him well down the field.
The 25-year-old Kaymer needs to finish in the top two here on Sunday to deny Briton Lee Westwood the chance of ending Tiger Woods`s 281-week spell as world number one.
Even though he found some form, Kaymer was again unable to make much headway at the tough southern Spain layout that hosted the 1997 Ryder Cup and where he clinched Europe`s rookie of the year award in 2007.
The U.S. PGA champion picked up three birdies but bogeys at the 15th and 18th pegged him back.
Westwood now looks almost certain to go to the top of the world rankings on Sunday despite being at home this week nursing an injured calf.
