The US are well and truly in the hunt for a record seventh Hopman Cup title after a 3-0 triumph over Spain in front of 4838 at Perth Arena today.
Rising star Sloane Stephens was too good for veteran Anabel Medina Garrigues in her 6-3 6-1 win before giant teammate John Isner did enough to overcome journeyman Daniel Munoz-De La Nava 6-3 6-4.
The American pair, who are ranked a combined 267 placings above the low-ranked Spanish duo, were unsure about teaming up for the first time in the mixed doubles and they showed it in the first set.
Games went on serve until the Spanish heaped the pressure on Stephens’ serve and got the breakthrough.
Both Medina Garrigues and Munoz-De La Nava were able to hold serve from there as they clinched their first set of the tournament.
Stephens and Isner steamrolled the eighth seeds in the second set, taking it 6-0 to force a match tie-break.
The US kept that momentum going to take the tie-break 10-4 and the 3-0 victory.
It tops a shocking two days for the defending champions, who also lost 3-0 to the Czech Republic yesterday.
They have a chance to redeem themselves against France on Friday.
The US will take on France on Wednesday.
