With just 18 holes remaining, South Korea's Lee Chang-woo sits on the cusp of a career-changing moment.
After shooting his best score so far in the Asia-Pacific Amateur Championship on Saturday, Lee's 69 was one of the best rounds of the day and put him atop the leaderboard at the Nanshan International Golf Club in Longkou City, China.
Last week playing in the Kolon Korea Open, Lee finished in a share of second place among the pros, including tying with Rory McIlroy.
The winner of this event will earn an invitation to the 2014 Masters as well as a spot in the International Final Qualifying for the Open Championship. The runner-up also receives a spot in the IFQ for the year's third major.
China's Dou Zecheng, the 16-year-old who led after the first round, is a shot back of Lee after a rebounding with a 69 on Saturday after a 75 on Friday.
Defending champion Guan Tianlang, the now-15-year-old Chinese star who set the Masters record for youngest player to tee it up in that tournament's history, rose on the leaderboard in round 3 into a tie for fifth place, but still sits 5 shots off the pace.
