Kaymer had three birdies and two bogeys
Lee Westwood is all but certain to become world number one with his top-spot rival Martin Kaymer languishing well down the Andalucia Masters field.
German Kaymer needs a top-two finish at Valderrama to stop Westwood ending Tiger Woods' 281-week reign at the top.
But a third-round 70 left Kaymer three over par, nine shots behind Northern Irish duo Graeme McDowell and Gareth Maybin, who led through nine holes.
Barring a freak final round, England's Westwood will topple Woods on Sunday.
The 37-year-old is currently recovering from a calf problem and does not intend to play again before the WGC-HSBC Champions event on 4 November.
Kaymer had started the day 11 shots off McDowell's lead after opening with a 72 on Thursday and following that up with a 75 in his second round.
The 25-year-old, therefore, required a sensational effort on Saturday to move up the leaderboard.
However, the US PGA champion had to be content with merely playing solidly, picking up only one shot - on the fourth hole - to reach the turn in 34.
He sank two more birdies at 14 and 17 but bogeys on 15 and 18 extinguished any slim hope he had of moving into contention.
Kaymer tops the European Tour money list, the Race to Dubai, from McDowell by almost a million euros with five events to be decided.
It is likely that US Open champion McDowell will close that gap on Sudnay with 500,000 going to the winner in Andalucia.
