But she then had a timely reminder of what can happen if concentration slips, as Vogele held her own serve and then broke Raducanu’s to end the Briton’s run, albeit somewhat against the run of play.

And the teenager’s response was similarly positive, as once again she broke back straight away to prevent her opponent from taking the momentum.

She then took the lead in the set 3-2 before an outstanding display of courage and determination to resist five break points in the sixth, although Vogele would go on to hold this time.

That wouldn’t be the case the next time the Swiss served, though, as she continued to struggle with the speed of Raducanu’s returns from the back of the court and the Briton won a tense game which went to deuce.

Raducanu closed out the game by eventually winning her seventh match point in a tense final game to set up a second round clash with world number 49 Shuai Zhang of China, who also won her opening match against Hailey Baptiste in straight sets.
