BANGKOK (AFP) - Fourteen year-olds Mima Ito and Miu Hirano on Saturday became the youngest ever winners at the US$1 million (S$1.3 million) table tennis World Grand Finals in Bangkok.

The schoolgirls took the women's doubles title, beating Natalia Partyka and Katarzyna Grzybowski of Poland 11-7, 11-6, 11-4, 11-5, to claim a US$40,000 share of the prize money.

The Japanese teens had already defeated the Polish women at the German Open this year and Ito said "we knew we could beat them, but of course this was a new match and it was a very special match."

"We are going to buy lots and lots of presents for our family and friends, we are so excited about this money," added Ito.

Japan's men's pair Kenta Matsudaira and Koki Niwa lost their final against South Korea's Cho Eon-Rae and Seo Hyun-Deok in a seven game thriller - 11-8, 10-12, 5-11, 12-10, 6-11, 11-6, 9-11.
