Coco Gauff overcame the trickiest test of her hunt for a second US Open title so far as she roared back from a set down to beat French Open champion Mirra Andreeva 2-6, 7-6(7), 6-2 – and book her spot in the semifinals.After the match, she admitted that she had been inspired by fellow American and semi-finalist Frances Tiafoe, who beat Alex Michelsen over five sets on Tuesday.’I think I had to reset,’ Gauff said of her choppy first set, and how she returned to demolish Andreeva. ‘I came out not feeling the ball, not giving her too many free points, Mirra was playing great.’In the bathroom, honestly I was thinking about Frances Tiafoe yesterday, and how he came back (against Michelsen).’I was trying to leave the court with no regrets.’The two-time major winner is set to play the newly crowned world No 1 Elena Rybakina next, who beat Zheng Qinwen earlier on Wednesday to claim her spot at the top of the women’s game. Coco Gauff screams with delight after sealing her place in the US Open semifinal Gauff threw her racket and looked to the heavens after beating Mirra Andreeva on Arthur AsheGauff also keeps hope alive of an all-American final on Saturday, with US No 1 Jessica Pegula due to face Aryna Sabalenka in their semi-final on the opposite side of the draw.But Gauff was by no means assured of a place in the last four after the first set, which saw the 2023 winner bamboozled by the Russian teenager.Andreeva hurtled out of the starting blocks to build a formidable 5-1 lead, with Gauff only capable of holding her final service game before the set break.Although the duo kept pace in the second set, Gauff cut a frustrated figure on-court, at times looking on the verge of tears as she remonstrated herself – and her players’ box – over her lack of form.The 22-year-old swiped the early break of serve to make it 4-2, but was immediately broken back by Andreeva, with neither woman holding onto their game until the match settled at 5-5. Andreeva was seeded No 5 but did not have enough to overcome Gauff and the partisan crowd Gauff faced match points but battled back to seal a huge win in front of the New York fansForcing a tiebreak, Gauff showed the very best of her level as she set up three match points before eventually sending the match to a deciding set.Backed by a wildly partisan crowd cheering on their former champion, Gauff didn’t slow down in the third as she broke Andreeva for 3-1, with the 19-year-old never again truly comfortable as her game slipped away from her and her error count rose.At 5-2, Andreeva’s frustration bubbled over, with the young star letting her racket fly, the instrument crashing into a pile of her belongings and forcing a cameraman to dodge out of the way. Andreeva then slumped into her chair, appearing to wipe her eyes before she returned to court.Gauff proceeded to serve out the match in style, once again burnishing her credentials as a favorite for the title.
