St Andrews' Ewan Scott is well-placed going into the final two rounds of the South African Stroke Play Championship.
Seeking to go one better than David Law, beaten in a play-off in 2011, Scott fired seven birdies in his second round 67 to move to six-under-par for the event.
At the Hyatt Regency Oubaai Golf Resort and Spa, 17-year-old Scott was briefly leading before finishing three shots off the pace.
The Boys' Performance Squad member is continuing the form that saw him shine in 2012, winning the Scottish Hydro Boys' Order of Merit, before starting 2013 with a bang by winning a gold medal for Team GB at the Australian Youth Olympic Festival.
Pretoria's Werner Ferreira overcame the disappearance of his sand wedge shortly before tee off and signed for a three-under-par 69 to lead the championship by one stroke.
Ferreira broke free of the three-way tie for the lead he was in after the first round and climbed to nine under par through 36 holes of one of the most prestigious amateur tournaments in South Africa.
His nearest challenger is South African number one and defending champion Haydn Porteous, who signed for a 67, including a double bogey on the par-five 18th, to finish on eight-under.
And on seven-under lies the pair of England's Joshua White and Australia's 14-year-old phenomenon Ryan Ruffels following their rounds of 68 and 71 respectively.
Another Australian in Brady Watt, ranked second in the world, produced a solid 67 to make him a threat amongst a group of players on six-under and also including Jovan Rebula, the nephew of Ernie Els.
The international leaderboard presents a strong possibility of the first foreign winner of the SA Stroke Play Championship since England's Gary Wolstenholme in George in 2002.
Of the other Scots, Blamore's Fraser McKenna made the cut (tied 35th) as did Adam Dunton of McDonald (tied 58th).
But there was disappointment for James White who missed the qualifying mark by a shot, with Graeme Robertson and Conor O'Neil also sitting out the final two rounds.
