Ren Yijia of China captured the second CLPG Tour title of her young career on Friday as the 15-year-old amateur birdied the final hole to win the Zhangjiagang Shuangshan Challenge by one stroke in Jiangsu province.

After starting the day four shots back of the leaders, the Dalian teenager closed with a four-under 68 for a 54-hole score of eight-under 208 at Zhangjiagang Shuangshan Golf Club, a Nelson & Haworth layout on an island in the lower reaches of the Yangtze River.

Shi Yuli and amateur Li Menghan, the overnight co-leaders, each closed with a round of one-over 73 to finish equal runner-up at the tournament. Pang Runzhi, Sui Xiang and Zhou Shiyuan, the country's top female amateur, also posted closing rounds of 73 to finish equal fourth.

Ren, who with Zhou and Xu Ying (73) will represent China at next month's Espirito Santo Trophy, the world amateur team championship, in Singapore, opened with consecutive birdies to start her round. After posting two bogeys and a lone birdie over the next 12 holes, the teenager made her charge late in the day in carding three birdies over the final four holes to secure the win.

"I'm really happy with this win. Last night I thought about going for the win, but this morning I just went through my warm-up and played my game as usual without paying too much attention to the scores. Only in the last few holes did I check the leaderboard. On the 14th hole I made a bogey and felt a bit low, but I came back strong with two birdies and then another one on the 18th to finish on top. That was a great feeling," said Ren who last year became the CLPG Tour's youngest champion when she won the Beijing Women's Challenge in May.

"Over the past year I've played a lot of tournaments, including international events, and gained valuable experience. After my first win I wanted to win again right away, but my results weren't good. It took time to settle down, and this year I've learned to keep a calmer mindset, enjoy my communication with my caddie, and play more freely. That has been the biggest improvement."
