Despite being just 17 years of age, Rublev has already been tipped for the top of the sport and he soon showed that he belonged in the company of the South African as they shared two tie-break sets.

However, the third went the way of Anderson after he struck late in the set, and another break of serve in the fourth left him on the brink of the next round.

Rublev continued to compete, but he had no answer to the serving of his opponent, who ended the contest with 32 aces to his name.
