Second seed Maria Sharapova suffered a shock 7-6 6-3 defeat to compatriot and wildcard Daria Gavrilova in the second round of the Miami Open.

Sharapova trailed 3-0 in the second set but battled back to 4-3 down before her serve was broken again by the 21-year-old who broke into the top-100 this week.

The pair had never met before and Gavrilova, who is based in Australia, was playing in her first Miami Open.

“I have been dreaming about beating Maria since I was probably 12 when I saw her win Wimbledon,” said Gavrilova who expects to receive her Australian citizenship later this year.

“I was probably visualising beating her since I was 12 but this was a bit harder than that.

“I thought I was very composed and just did my best. I was believing.”

Sharapova said she had lacked patience at times and attempted too many winners but she was philosophical about her loss.

“It’s sport, and I happened to lose the match. Of course it’s a bit of a surprise... I’m expected to win,” she said.

Venus Williams eased into the third round with a comfortable 6-3 6-2 win over Poland’s Urszula Radwanska while Caroline Wozniacki also progressed after beating American Madison Brengle 6-0 6-1 to set up a meeting with Estonian Kaia Kanepi.
