Chilean qualifier Alejandro Tabilo advanced to the quarterfinals at the Chengdu Open by cruising past Italian No. 2 seed Luciano Darderi 6-4, 6-3 on Friday in China.

Tabilo, who's fallen outside the top 100 in the world rankings after rising as high as No. 19, smashed 12 aces with only one double fault, went 4-for-4 saving break points and converted both his opportunities to break Darderi's serve.

Another big winner was No. 4 seed Brandon Nakashima, who ousted defending champion Juncheng Shang of China 7-5, 6-3. Nakashima will meet fellow American Marcos Giron in the next round after Giron eliminated No. 8 seed Lorenzo Sonego of Italy 6-4, 6-4. Tabilo will face Aussie Christopher O'Connell, a 6-2, 6-4 victor over China's Yi Zhou.
