Aussies Nich Kyrgios and Daria Gavrilova have claimed this year’s Hopman Cup after beating Ukraine in Saturday’s final in Perth.

Kyrgios maintained his perfect record in the singles to seal Australia’s first title in 17 years when he beat Alexandr Dolgopolov 6-3, 6-4.

In what was a great tournament for the 20-year-old, Kyrgios won all four of his singles rubbers, including the scalp of Andy Murray and combined with Gavrilova for an unbeaten doubles run.

Earlier, Gavrilova had given the Australia Green pair a 1-0 advantage following a straight sets win in her singles rubber.

The world No.36 defeated 19th-ranked Elina Svitolina 6-4, 7-6 (8-6) after saving set points in the second-set tie-breaker.

The Hopman Cup crown will no doubt give the Aussie duo huge confidence heading into the Australian Open which starts on 18 January.

“It means a lot, it is my first real title to have won,” Kyrgios said.

“It is the perfect way to start the year, I haven’t lost a match yet and I am riding a lot of confidence into the Australian summer.

“I have known Dasha [Gavrilova] for a long time and it is pretty special.”

Gavrilova trailed 6-1 in the second-set tie-break, before reeling off seven straight points to secure a famous victory.

“I played a tournament in under 12s, and it was a super tie-breaker, and I was down 9-1 and I ended up winning,” Gavrilova said.

“I just literally told myself to settle down, just stop thinking of everything. Just think about how to win every point.

“It is the biggest event I have ever won and just representing Australia for the first time and winning this title straight away is amazing.”

Australia had won the Hopman Cup only once before, when Mark Philippoussis and Jelena Dokic lifted the trophy in 1999.
