Scott Jamieson will seek to not only end a four-year European Tour winless drought but also see the Scottish flag go to the top of the mast for a first time in some 15 months heading to the final day of the Tshwane Open.

Jamieson birdied the 18th on day three to ensure he and Swedish rookie Alexander Bjork were tied at the top on 13-under par and both posting rounds of 68.

South African Dean Burmester and Spain’s Jorge Campillo and each shooting 65s were next best and just a shot back at 12-under par.

Indeed there is 16 players within five shots of the lead on the Pretoria course.

Björk had opened up a two-shot lead at one point but there was a four-way tie as the leading duo came up the last, with a pair of birdies edging them back ahead.

Björk is contesting just his ninth European Tour event while Glasgow-born Scotsman Jamieson teed-up this week in his 188th Tour event and seeking just a second success after capturing the rain-shortened 2013 Nelson Mandela Championship.

“I’m in a great position to go out and try and win the tournament tomorrow,” said Jamieson. “Yet again, I was really good tee to green but I felt as if I left quite a few out there on the greens. I wasn’t at my best there but tomorrow’s another day and I have a chance of winning.”

It is also some 15 months since a Scot won on the European Tour and that was Russell Knox in capturing the 2015 WGC – HSBC Champions event.

Björk put his approach on the first to seven feet and opened with a birdie to move a shot ahead. The 26 year old was clearly zoned-in and got within ten feet on the next to make another birdie and the lead was quickly up to two shots.

Jamieson then holed a ten-footer of his own on the third to cut the gap back to one and a  run of pars followed before Björk rolled in a 15-foot effort on the seventh to re-establish his cushion.

A Jamieson birdie on the par five ninth then left the tournament finely poised heading into the back nine.

The 33 year old bogeyed the tenth after getting in trouble off the tee and a wedge to tap-in range on the 12th from Björk really applied the pressure but Jamieson holed from 12 feet as both men made birdies.

Jamieson then holed an impressive 18-footer on the next and with Björk dropping his first shot of the day, the pair were tied at the top.

The 15th saw both leading men make bogeys with Jamieson finding a greenside bunker and Björk missing a short one and all of a sudden Burmester and Campillo – both in the clubhouse – shared the lead.

“I’m very pleased with my position,” said Björk. “It was a solid round today. I got off to a very good start with two straight birdies. Things were a little bit worse in the middle of the round but I finished with a good birdie on 18, so I’m looking forward to tomorrow.

“I’ve been in this position a few times on the Challenge Tour, but it’s bigger here – more people, more television and everything – so I’m interested to see how I handle it tomorrow. It’s going to be a lot of fun to play.”

Home favourite Burmester started with a bogey but then made four birdies in a row and added another after a smart up-and-down on the ninth before finishing birdie-birdie with the help of a lengthy putt on the 17th.

Spaniard Campillo had an even better end to his round, going birdie-birdie-eagle over the final three – holing from a bunker on the last – after turning in 33 with three birdies and a bogey.

Finn Mikko Korhonen was then at 11 under, a shot clear of South Africans Thomas Aiken and Peter Karmis, England’s Oliver Fisher and James Morrison, and Australian Ben Eccles.

Korhonen made birdies on the second and third and smart up-and-downs from sand on the par five ninth and 12th in his bogey-free 67.
