Belarus second seed Aryna Sabalenka had the honour of being the first winner at Wimbledon in two years when she downed Romanian qualifier Monica Niculescu 6-1, 6-4 under the roof of Court One while former US Open champion Sloane Stephens knocked out Czech 10th seed Petra Kvitova, the 2011 and 2014 champion, 6-3, 6-4 in the biggest upset of the women’s draw on the first day.

Sabalenka fired 48 winners past Niculescu in what was only her second main-draw win at Wimbledon.

“I was nervous a little bit because I haven’t played on the show courts at Wimbledon,” said Sabalenka who has yet to make the last-eight of a major.

Later, seventh seed Iga Swiatek passed the Hsieh Su-Wei test, beating her 6-4, 6-4 in one hour and 15 minutes.

Garbine Muguruza, the 2017 winner, needed just under an hour to see off France’s Fiona Ferro 6-0, 6-1.

Another Grand Slam champion, Sofia Kenin, also advanced, with the fourth seed getting past Chinese qualifier Wang Xinyu, 6-4, 6-2,
