Team USA are United Cup champions once more after triumphing in the final 2-0 over Team Poland on Sunday night.
With Coco Gauff prevailing over Iga Swiatek in the women's singles leg, Team USA placed one hand on the silverware.
The team's victory was later sealed after Taylor Fritz hosed down a fightback from Hubert Hurkacz to put the last nail in Poland's coffin.

Fritz held off Hurkacz with a tight 6-4, 5-7, 7-6(4) victory as the Pole endeavoured to keep his side in the hunt.
As Fritz snared an advantage to take the opening set 6-4, Hurkacz upped his game to keep within striking distance.
In a turn of the tide, from the beginning of the second set, the pair could not be split.
After the second set played out on serve with neither player willing to give an inch, Hurkacz broke in the 12th game to take it out.
It was a similar story in the deciding third set before a late shoe change for Hurkacz late frustrated Fritz as he clung to life to force a seven-point tiebreak for the match.
A long forehand from Hurkacz gave Fritz the mini-break before he consolidated his serve and then served out the match.
Earlier, in the opening leg, Guaff got the better of Swiatek 6-4, 6-4 in a thrilling match of strength and speed.
In an arm-wrestle of a first set which featured five breaks of serve, Gauff triumphed 6-4.
Gauff initially broke Swiatek's opening service game before the world No.2 immediately broke back.
With tension building, Swiatek then broke again and Guaff broke back to level the set at 3-3.
With the set wrestled back onto serve, Swiatek could not hold in the 10th game to stay in the contest— stress clear on her face.
The second set played out on serve until Swiatek outlasted Guaff in a gruelling rally which laid the foundations for a break and a fleeting swing in momentum.
In a game lasting just under 10 minutes, Guaff required three break points to equalise.
"This is absolutely nuts," Sam Smith said in commentary for Nine regarding the seesawing affair between the two stars.
Seemingly struggling with a right leg complaint, Swiatek left the court for treatment.
But after returning from a medical timeout, Swiatek was unable to serve out the game to extend the match.
The mixed doubles leg of the tie was not required.
Gauff was later named the tournament's MVP.
Team USA is the first nation to win two United Cup titles after triumphing in the inaugural event in 2022/23.
