Allan Versfeld shot a third-round 71 in the first stage of European Tour Qualifying School at Wychwood Park on Thursday and returned to tied sixth ahead of the final day.
The top-25 make the cutoff, and while countrymen Tyrone Mordt and Le Roux Ferreira are both at one-over and must work to maintain their share of 15th, Versfeld is set to progress.
The experience gained from three top-10 finishes on the Sunshine Tour paid off for Versfeld, whose composure in round three was rewarded by a one-under-par score.
The result returned Versfeld to a share of sixth, a position he held with his opening 70, but subsequently fell from after carding a disappointing 73 on day two.
Englishman Steven Uzzell continued to lead after maintaining his score of eight-under and holds six strokes over Versfeld.
Further afield are Mordt and Ferreira, tied for 15th and two strokes within 25th-place cutoff line ahead of the final round.
Mordt carded level-par to remain at one-over, while Ferreira struggled to find the cup and shot 75.
Andrew Georgiou managed a 73, but shared 30th at the end of the third round and needs a decent finish to ensure his progression.
With Darryn Lloyd at seven-over and Nico Els at 12-over some South Africans are unlikely to make the next stage, and both players have mammoth tasks facing them in round four.
Versfeld showed his class as a rookie on the Sunshine Tour this year and with his ticket to the next stage a mere 18 holes away, he looks good ahead of the final day.
