China bagged home three gold medals at the ITTF Pro Tour English Table Tennis Open while South Korea's Kim Kyung Ah and Park Mi Young snatched the women's doubles title here on Sunday.

Ma Long, 21, became the biggest winner at Sheffield as the Chinese star won in both the men's singles and doubles events.

In the singles final, the world No. 2 left few chances for his seasoned teammate Ma Lin by beating the reigning Olympic champion 11-9, 11-6, 11-8, 11-8.

Earlier, Ma paired up with veteran Wang Liqin to defeat Japanese Seiya Kishikawa and Jun Mizutani in seven games in the doubles final.

"I didn't come here in good shape as I have competed in three big events consecutively," said Ma. "But I tried my best to tune up and felt better and better in process of the competition."

The 32-year-old Kim Kyung Ah showed scintillating form as she overplayed China's promising star Ding Ning in the women's singles quarterfinals.

Although top seed Liu Shiwen depressed her in Sunday's semifinals, Kim displayed her outstanding defense later in the doubles final, partnering Park, to disappoint Chinese duo Chang Chenchen and Guo Yan 8-11, 11-3, 11-13, 12-10, 9-11, 11-5, 11-6.

Guo found some comfort from the women's singles title after overcoming top seed Liu 11-9, 11-13, 11-7, 16-14, 11-6.

Compared with teenage teammates Liu and Ding, the 27-year-old Guo is regarded as a veteran. She is fighting for her first appearance at the Olympic Games.

"I wouldn't regard myself as a veteran because I don't want to lose any passion for the competitions. I'm looking forward to the 2012 Olympic Games. Therefore, I need to play wholeheartedly and passionately," said Guo.
