Chinese teenager Cheng Zhu took out the men's singles title at the ITTF Argentina Open in Buenos Aires on Sunday.
Fourth seed Cheng, 17, was crowned world champion after defeating sixth-seeded compatriot Fei Xue 11-7 11-9 11-3 9-11 7-11 11-8 in the Argentine capital.
"It is not easy to win a World Tour title, so this is amazing; my opponent was very strong and it was not an easy match," Cheng said afterwards.
"I never thought it would be easy; when I was up 3-0, I was prepared for my opponent to come back.
"I was nervous when it was 3-2 as my opponent changed his serve which I struggled against but since I was mentally prepared for a tough math I was able to fight back and win."
China also had a winner in the women's draw thanks to He Zhuojia, who accounted for countrywoman Fan Siqi.
He - the 15-year-old third seed - won 8-11 11-3 7-11 11-5 11-8 11-9.
"It is amazing to be the champion here," said He.
"Words cannot explain how happy I am; it was tough to play against my friend in the final but there was not too much pressure, as whoever won, China won the gold which is good for us."
