Wu Ashun fired a second-round 66 at the KLM Open to open up a three-shot lead over England's Jonathan Thomson in the Netherlands.
The Chinese golfer held a one-shot advantage after day one in Spijk and carded seven birdies and two bogeys to get to 12 under, although Thomson threatened to overshadow him with a brilliant birdie run.
The 22-year-old holed a 40-foot putt on the 10th and then made six birdies in a row to turn in 28 and raise hopes of a first round of 59 in European Tour history.
Thomson – at six foot nine, the tallest player in European Tour history – found the hazard on the first and a bogey stalled his momentum, eventually coming home in level par 35 to sign for a 64.
After losing in a playoff in Denmark recently, Thomson is edging closer to keeping his place on Tour for next season, quite an achievement for a rookie who battled leukemia for five years as a child.
“I am hitting some great form and playing well, my confidence is also getting higher and higher and that’s all that matters to me at this part of the season,” he told europeantour.com.
“Experiences like I had in Denmark are invaluable and every single week you have to go out and just draw on them.”
Wu is a two-time winner on the European Tour and made birdies on the first, second, sixth, 10th, 12th, 16th and 17th to go with bogeys on the fifth and 15th.
Another Chinese player in Li Haotong was at eight under alongside Scot David Drysdale, with England's Chris Wood a further shot back.
Pádraig Harrington carded a one-under 70 in his second round to move to four under and a share of 21st position.
Paul Dunne dropped five shots over his first three holes after starting double-bogey, double-bogey, bogey to go out in six-over 41.
Although he carded four birdies in five holes on his back nine, including three-in-a-row from the second, he ended one shot outside the cut on level par after completing a one-over round of 72.
