(CNN) -- Germany's Martin Kaymer and Jarmo Sandelin of Sweden hold a one-shot lead going into the final round of the Alfred Dunhill Links Championship after battling performances in tough conditions on Saturday.
The umbrellas are up as Kaymer tees off on the 18th at Carnoustie.
Kaymer shot a one-over 73 and Sandelin carded a 72 at a cold and windswept Carnoustie to set the pace at 210 - six-under-par.
Sandelin's Swedish compatriot Magnus Carlsson looked set to lead the tournament but double bogeyed the 17th and is one-shot behind.
This year's double major champion Padraig Harrington is also well-placed for a victory that would all but clinch the European order of merit crown.
The British Open and PGA Championship winner struggled to the turn at Carnoustie in 40 but came home in 34 with birdies at the 12th and 15th and is in a group with Thongchai Jaidee of Thailand and overnight leader Austria's Markus Brier at four-under.
Lee Westwood, his nearest rival in the race to be European number one, slipped back to two-under with a four-over 76.
Another in-form Swede, Robert Karlsson, is also in contention at three-under as he steps up his challenge to Harrington in the money list.
Young hopeful Kaymer, who narrowly missed out on the European Ryder Cup team, opened with a 65 at Kingsbarns and he lay second overnight after a 72 at St Andrews.
"This was the toughest day on the toughest course and it was the worst weather this week," the 23-year-old Kaymer told Associated Press.
"You have to accept some bunkers and some bogeys."
All the players return to St Andrews for Sunday's final round after playing at the three courses in rotation in a unique format for the European Tour.
They have been accompanied throughout the tournament by amateur partners with celebrities from the world of sport and entertainment taking part in the event.
