Five-time winner Tom Watson continues to lead the Open after the third day at Turnberry despite a strong showing by Ross Fisher and Lee Westwood.
The 59-year-old American ended the day on four under for the tournament while Fisher posted a 70 and is just one shot behind.
Australian Matthew Goggin is also three under after a 69 with Westwood, the online betting favourite to win the tournament, one shot further behind alongside Retief Goosen.
Watson ended a rollercoaster day still in first place after bogies at the sixth, ninth, 12th and 15th holes were followed by birdies at the 16th and 17th.
Bryce Molder of the USA posted the best score of a wind-battered day with a three-under-par 67 and is on par for the tournament going into the final day.
A succession of bogies in his second and third rounds has put Padraig Harrington out of the running to win his third successive Open. Harrington finished with a 76 and is now nine over for the tournament.

In cricket, England have set up a winning position after dominating the third day of the second Ashes Test against Australia at Lord's.
The hosts lead by 521 runs with two days to go, having reached 311-6 in their second innings after bowling the Baggy Greens out for 215 and opting not to enforce the follow-on.
Resuming on 156-8, the tourists came close to denying England the option of the follow-on, before eventually falling just short. Graham Onions eventually had Nathan Hauritz caught at second slip by Paul Collingwood for a composed 24.
The innings was over when Peter Siddle nicked a wide one from Onions to Strauss and departed for a well-made 35, leaving Ben Hilfenhaus six not out and Australia ten short of avoiding the follow-on.
England chose to bat again and Alastair Cook and Strauss made a fluent start against a lack-lustre Aussie attack.
Off-spinner Hauritz then made a double breakthrough to slow the charge.
He trapped Cook leg before wicket for 32, before Strauss edged a turning delivery to Michael Clarke at first slip to depart for the same score.
After tea, bad light ensured that England batted on, with Hauritz taking his third wicket as Ravi Bopara (27) edged a catch to Simon Katich at short leg.
Kevin Pietersen made 44 before edging Siddle to Brad Haddin, before Matt Prior gave the innings renewed impetus with a quickfire 61 from just 42 deliveries before he was run out.
Collingwood recorded a half-century before falling to the Siddle-Haddin combination, with Andrew Flintoff 30 not out when rain brought an early end to the day's play.
In the Tour de France, Russian Serguei Ivanov claimed victory in the 14th stage of the race, while in boxing Amir Khan beat Andreas Kotelnik to win the WBA light-welterweight crown.
