Only two other British men have made it to the quarter-final stage at Melbourne - Andy Murray and John Lloyd (way back in 1985).

"Through to my first quarter-final - I am very happy," said the 23-year-old Brit.

"It was a close first set and I didn't feel I got the best start. He was hitting the ball very clean.
