St Andrews - South Africa's Branden Grace equalled the European Tour record when he shot a blistering 12-under-par 60 midway through the first round of the Dunhill Links Championship on Thursday.
Grace, a triple winner on the tour in 2012, clipped two strokes off Lee Westwood's previous Kingsbarns record of 62 set in 2003 after finishing with five straight birdies.
Frenchman Victor Dubuisson was two shots off the lead on 62 after breaking the course record at St Andrews, one of three layouts being used this week.
Grace became the 14th player to shoot a 60 on the European Tour.
Northern Ireland's Darren Clarke, the 2011 British Open winner, is the only man to card two 60s on the circuit, in 1992 and 1999.
Long-hitting Frenchman Dubuisson broke the previous St Andrews best of 63 held by world No 1 Rory McIlroy, former top-ranked player Luke Donald and fellow Briton Simon Dyson.
Young Dane Thorbjorn Olesen was also on form at the famous Old Course, returning a 63 in the $5m Dunhill pro-am tournament.
Ryder Cup hero Martin Kaymer (70) played at the more testing Carnoustie layout and missed a par putt at the 18th of a similar length to the one he holed in Chicago last Sunday to win the trophy for Europe.
"The putter was not really hot but in general you've got to play solid at the toughest course we play here," the 2010 US PGA champion told reporters.
"It's a very nice feeling to come here after Sunday. A lot of people told me it was their best sporting experience on TV," added the German.
Europe came back from 10-6 down to score a stunning 14 1/2 - 13 1/2 win over United States in the biennial team event.
Kaymer's Ryder Cup team-mates Paul Lawrie (75) and Peter Hanson (72), both playing at Carnoustie, also found the going tough.
British Open champion Ernie Els returned a 73 at Carnoustie where the best score midway through round one was a 67 by England's Oliver Wilson.
