Long through while Marin fails

Chen Long advanced to the semi-finals of the men's draw while women's top seed Carolina Marin was knocked out of the THAIHOT China Open on Friday.

Long was too hot to handle for Ajay Jayaram on the courts of Haixia Olympic Sports Centre in Fuzhou. The Chinese star defeated Jayaram 21-15, 21-14 to advance to the final four.

Long will face third seed Viktor Axelsen, who eased past Takuma Ueda of Japan 21-11 , 21-6 in just 30 minutes.

Elsewhere, Denmark's Jan O Jorgensen edged fifth seed Tian Houwei 14-21, 21-16, 21-14 and Iskandar Zulkarnain beat Bin Qiao 21-19, 21-7.

In the women's draw, Marin was beaten at the quarter-final stage by fifth seed Tzu Ying Tai 21-10, 22-10 in a pulsating affair. 

Tai will face Sun Yu after the Chinese shuttler rolled over Line Kjaersfeldt 21-19, 21-3.

The other semi-final will feature seventh seed Sindhu V Pusarla and sixth seed Ju Hyun Sung after they eased through their quarter-final clashes.
