The youngest player to compete on the European Tour missed the cut, while Mikko Ilonen of Finland tied the course record with a 9-under 63 Friday for a three-shot lead at the China Open.
The 12-year-old amateur Ye Wocheng missed the cut at 14 over after a pair of 79s. But China's Dou Zecheng became the youngest at 16 to make the tournament cut with a 2-under total.
Ilonen birdied four of his last five holes to finish at 12 under and move ahead of Australia's Brett Rumford and Thailand's Kiradech Aphibarnrat, who had 67s.
Ilonen matched the Binhai Lake course record set last year by Sweden's Alexander Noren. He also equaled his lowest round at the 2009 Madrid Masters.
