After a series of lovely backhands at the net, Zarazua gets lucky and one snares the cord to leap over Raducanu’s head and land beyond her for a bashful opening point.
Raducanu’s retort is to push her back to the baseline and fire at her until she blinks, which Zarazua does with a shaky forehand which flies out as she runs up the court.
After hitting too long to make it 30-all, Raducanu lets out a long cry of relief after Zarazua does the same, moments after being spurred on with cries of ‘come on, Emma!’ from the crowd.
At 40-all, after another mishit, Zarazua wins the advantage, on the brink of the match’s first break. After a barnstorming serve, Raducanu smacks a backhand across court which is called out – only for the Briton to call in HawkEve. And it’s in! By a whisker.
Raducanu’s advatage comes with a powerfully struck winner at the net, and another fist-bump. Again looking frightening as she switches between crosscourt forehands and backhands, Raducanu holds when Zarazua hits long.
Nervy, but she got her hold in the end.
