Colin Montgomerie's eight-over-par round of 79 on Saturday means he will lead off the final day of The Open and play on his own.

It leaves the Scot 12 over par for the tournament and at the bottom of the 81-man pile.

This comes after Royal Troon member Montgomerie hit the first shot of the 145th Open Championship on Thursday.

"It has been a positive week apart from today. I played particularly badly," he said.

Montgomerie will begin his final round at 07:40 BST.

The 53-year-old's third round was blighted by two double bogeys and six bogeys on the South Ayrshire links course.

Birdies at the fifth and 10th holes were scant consolation in a day that did not work out well for any of the home talent still involved.

Russell Knox was the closest Scot to the leading pair of Phil Mickelson and Henrik Stenson at the start of the third round, but two bogeys in his first five holes started his slide towards a four-over-par 75 that left him four over for the tournament.

There was the bonus of a birdie at the 100-yard Postage Stamp eighth hole for the Inverness man; then another at the par-five 16th.

Knox tees off with America's Rickie Fowler on Sunday at 10:35 BST.

European Ryder Cup vice-captain Paul Lawrie bogeyed the first two holes of his third round which was an early blow to any hopes of an upward surge on what is labelled "moving day".

An admirable eagle at the par-five sixth hole neutralised that bad start, before three more bogeys on the back nine meant the Aberdonian posted a three-over-par 74 to go into Sunday seven over for the tournament.

Lawrie tees off with Masters champion Danny Willett on Sunday at 09:00 BST.
