LIVERPOOL, England, Sept. 30 (Xinhua) -- Top seed Ma Long knocked out Chinese teammate Xu Xin 4-0 with an exhibition of wonderfully aggressive table tennis at the men's World Cup here on Sunday.

Ma, who lost to Xu in the China Open early this year, breezed past Xu 11-4, 11-4, 11-4, 11-8 in a match which had been originally expected to be difficult.

The Olympic team champion will meet Germany's Timo Boll in the day's final. Boll, a twice champion, had defeated three-time titlist Vladimir Samsonov of Belarus 4-2 in the day's other semifinal.

Ma had previously competed twice in the World Cup but was stopped at the semifinals on both occasions. He was eliminated by Boll in 2008 and Samsonov in 2009.
