"I'm a little overwhelmed but very happy," said Gilliver, who was disappointed with his last-16 elimination in the sabre on day one.
"Maxim has been a huge rival of mine for years, so I just focused on my own game plan and executed it as best I could."

"To come through in straight sets today and 3-1 yesterday is pretty good but I know bigger challenges are in front of me in the quarter-finals and that is what I am thinking about now – one match at a time so we'll see who I get in the draw and let's go," he said.
