Australia’s Daria Gavrilova insists the hard work has paid off after finishing her Hopman Cup campaign with victory over Coco Vandeweghe.

The world No.25 bounced back from two singles losses in Perth to defeat the American 6-3 4-6 7-5 in front of an ardent home crowd.

Gavrilova said her singles win gave her an important confidence boost heading into the Sydney International, which starts on January 8.

“I really wanted to get that win, because coming into Sydney next week without winning a match is not the best feeling,” Gavrilova said.

“I played two three setters, and that’s good for my match conditioning. Overall I’m happy with my week. I felt like I played a lot better than my first match.

“Tonight, I think it all paid off. All the hard work, and thinking positive.”

Gavrilova reached the fourth round of the Australian Open last year on the back of her Hopman Cup title success alongside Nick Kyrgios.

The 22-year-old stated she wasn’t putting too much pressure on herself to repeat those heroics.

“I’m not thinking about Aus Open just yet,” Gavrilova said.

“I’m going to play Sydney, give my best, and not think of my result last year.

“Last year I didn’t put any expectations on myself, so I’m going to try and do the same, even though it’s pretty hard.”

Earlier on Thursday evening Nick Kyrgios fell in straight sets to Jack Sock before the US prevailed 4-1 4-1 in the Fast4 mixed doubles to progress.

The US will take on either Switzerland or France in Saturday’s final.
