Nigerian tennis star
Aruna beat Chilean Gustavo Gomez in four straight sets (11-2, 11-7, 11-5, 11-3) to progress to the next round where he will face Denmark.
Another Nigerian Segun Toriola could not progress following his lost 11-8, 11-6, 11-5, 11-1 loss to Mattias Karlsson of Sweden.
Speaking after his loss, Toriola said he lost because he wasn’t familiar with the ball.
"It was a very difficult match for me because the ball was not bouncing as I had expected and this sometimes made the ball to stay on table," the 42-year-old told the ITTF official website.
"Also, my opponent was using pimples on his forehand and I was trying to avoid playing to his forehand but it was very hard for me to achieve this.
"For me, I think the new ball has not helped any player because it was too slow on the table compared to the ball used during Rio Olympic Games. There should be long time awareness on the change of ball and this has really affected a lot of players.”
Another Nigerian Olufunke Oshonaike has also exited the competition after losing to Asian Champion and world number nine Miu Hirano.
Oshonaike lost four straight sets (11-8,11-2,11-4,11-1) to Hirano but said she is proud of herself after playing with a leg injury.
"I lost but I'm so very proud of myself because I played very well with my leg injury. It's a great privilege for me to still be wearing my green white green to represent my country NIGERIA on the Centre table,” she wrote on her Facebook page.
"Thank you all for your love and support. Though we all sponsored ourselves down here but I still love Nigeria so much and I know that one day it will be better."
