NICK Kyrgios and Lleyton Hewitt say Australia are capable of ending a 14-year Davis Cup title drought because Kyrgios has defeated every other singles player in the event.
Australia made the semi-finals in 2006 and 2015 since its last Davis Cup title in 2003.
"I think we can win it. I've beaten every other singles player,'' said Kygrios, referring to Serbia's Novak Djokovic, Belgian David Goffin and France's Lucas Poiulle among other players contending for the 2017 Cup.
"Everything needs to fall into place. But it's not easy to beat Thommo (Jordan Thompson) over five sets. He's got the heart of a lion.''
Belgium led their home quarter-final against Italy 2-1 and if they advance, their semi-final against Australia in September would be in Belgium.
An Italian win would see them play a semi-final in Australia and Hewitt would no doubt consider using Tennis Australia's portable grass court.
A home semi-final would lead TA to consider bringing a second tie back to Pat Rafter Arena within the space of five months, with Perth and Sydney alternatives.
"We have a good shot (of winning this year). It's hard to beat a team that wants to be there and pushes each other,'' Australian captain Hewitt said.
"To beat a full-strength, quality US team, this is one of our best wins in a long time.
"I wanted to get revenge (for Australia's 2016 loss to the United States at Kooyong).''
An attendance of 16,403 over the three days gave Tennis Queensland officials every right to argue that another tie come to Rafter Arena soon.
Kyrgios said he was not surprised to see Sam Querrey drafted in to play him after American No.1 Jack Sock had played singles and doubles on the first two days.
Observing the enthusiasm in Brisbane, it's hard to credit that member nations will vote in August on far-reaching Davis Cup reforms including best-of-three set matches played over two days.
US captain Jim Courier says he has maintained for years that instead of Davis Cup being played over four weeks each year it should be held in one location as a two-week event, except in Olympic Games years.
