Coco Gauff and Christian Harrison<\/a> continued their United Cup<\/a> mixed doubles heroics in Perth Wednesday to lead the United States into the semi-finals of the mixed teams\u2019 tennis tournament.<\/p>\n Rallying from a set down against an inspired Stefanos Tsitsipas<\/a> and Maria Sakkari, Gauff and Harrison won their third consecutive live mixed rubber 4-6, 6-4 10-8 on their third match point to keep alive the country\u2019s hopes of claiming a third United Cup<\/a> title in the past four years. <\/p>\n The United States will now travel to Sydney to play the winner of the Poland-Australia quarter-final. Today\u2019s other quarter-final in Perth sees Switzerland play Argentina. <\/p>\n “I’m really happy that we’re able to move through,” Gauff said. “I felt I was playing really good today and that Christian was playing very well as well, and I knew that once we got some opportunities it would eventually swing out way.”<\/p>\n In a rollercoaster quarter-final, Gauff gave the Americans an early lead with a 6-3, 6-2 win over Sakkari. But Tsitsipas responded with a 6-4, 7-5 triumph over World No. 9 Taylor Fritz<\/a> \u2013 his first Top 10 victory in more than 18 months. <\/p>\n \u00a0“I was fighting for the team and it was such a great match from my end,” a delighted Tsitsipas said. “It’s pretty straight forward when you are 0-1 down; I was aware of the level I needed to bring onto the court today. I felt I owed it to my team.<\/p>\n “Before I went to bed last night I was already visualising how the match was going to go. I was already playing it in my mind and I’m so happy to win exactly the way I planned. I was especially pleased with my serve and how I dealt with the pressure moments with a clear head.” <\/p>\n Putting 84 per cent of first serves into play in the first set put the Greek in an aggressive mindset. He fired an ace to fight off a set point at 4-5 in the second set and broke Fritz in the following game to set up the win. He won 80 per cent of first serves in the match. <\/p>\n Tsitsipas improved to 9-2 at United Cup<\/a> in singles. It was his first Top 10 win since defeating No. 5 Alexander Zverev<\/a>, No. 2 Jannik Sinner<\/a> and No. 10 Casper Ruud<\/a> to win the 2024 Rolex Monte-Carlo Masters<\/a>.<\/p>\n
