Carolina Marin into Hong-Kong Open semis

The Spanish player had her sights firmly set on her sixth big title of the year as she dismissed Porntip 21-12, 21-13 in 42 minutes.

Carolina Marin has had a strong year, winning the world title in August and shooting up the rankings to number one after starting the year ranked eighth.

World Champion Carolina Marin brushed off Thailand's Porntip Buranaprasertsuk to book her place in the Hong Kong Open semi-finals on Friday.

The Spanish player had her sights firmly set on her sixth big title of the year as she dismissed Porntip 21-12, 21-13 in 42 minutes.

Marin has had a strong year, winning the world title in August and shooting up the rankings to number one after starting the year ranked eighth.

"I am very happy with my performance because last week I lost against Wang Shixian, it wasn't a good game for me," said Marin, referring to the Chinese world number six.

"But I changed my (mindset) because I want to get the title here."

In the men's competition, former world number one Lee Chong Wei will meet rival and top seed Chen Long of China later Friday in the quarter-finals.

The meet is being billed as a grudge match after Lee beat Chen in Sunday's China Open final.

The Malaysian is on a winning streak after taking back-to-back titles in China and France as he made a strong return following an eight-month doping ban earlier this year.

Overnight hometown hero Angus Ng, who downed Chinese legend Lin Dan in the second round, will meet Chou Tien-chen of Taiwan later Friday to fight for his place in the semi-finals.

Hong Kong's Ng lost to Chou in the quarter-finals of the French Open last month — the first time he had reached the last eight at a Super Series tournament.
