Iga Swiatek\u2019s reign as US Open champion, and world number one, was ended by her nemesis Jelena Ostapenko.<\/p>\n
The 22-year-old Pole had not dropped a set on her way to the fourth round, but she had never beaten Ostapenko in three previous career meetings.<\/p>\n
Swiatek took the first set with relative ease but then Ostapenko\u2019s sledgehammer of a forehand started finding its mark to level the match.<\/p>\n
A one-sided final set saw former French Open champion Ostapenko triumph 3-6 6-3 6-1.<\/p>\n
Swiatek\u2019s defeat means that Aryna Sabalenka of Belarus will take over as world number one after the tournament.<\/p>\n

Ostapenko will face Coco Gauff in the quarter-finals after the teenager ended the grand slam comeback of mother-of-two Caroline Wozniacki.<\/p>\n
The 19-year-old came from a break down in the first and third sets to win both and complete a 6-3 3-6 6-1 victory.<\/p>\n
Wozniacki\u2019s return has been one of the stories of New York this year, having come out of retirement after more than three years and two children later.<\/p>\n
The 33-year-old former world number one has looked as though she has never been away, but a fired-up Gauff proved just too strong in the deciding set.<\/p>\n
Wozniacki got off to a dream start with a break in the first game and a 2-0 lead.<\/p>\n
But Gauff quickly got back on the board, levelling at 3-3 before going on to clinch the first set without dropping another game.<\/p>\n
Wozniacki cranked up the pressure in the second and Gauff started feeling it as her suspect forehand began to misfire and she was broken for 5-3 as the Dane levelled the match.<\/p>\n
I grew up watching Caroline…so to be on court with her today was an honour<\/p>\n
Gauff looked uncomfortable as she dropped serve again at the start of the decider, but after pointedly ignoring the advice of coach Brad Gilbert, the wound-up American began firing backhand winners as if they were going out of fashion.<\/p>\n
She reeled off the next six games to clinch the victory and let out a loud scream of triumph after converting match point.<\/p>\n
\u201cDefinitely getting it to 2-1 (in the third set) was the turning point,\u201d said Gauff.<\/p>\n
\u201cI got broke and I showed I was still in the match. I started to go for my shots.<\/p>\n
\u201cCaroline, it\u2019s like she\u2019s never left, the level she played was amazing. It\u2019s weird because I grew up watching Caroline and when she won the Australian Open, so to be on court with her today was an honour.<\/p>\n
\u201cShe definitely gets to a lot of balls. I felt a bit like I was playing myself. I knew I had to play aggressive and go for my shots. In some moments I miss but I was happy I could get back and refocus.\u201d<\/p>\n

<\/p>\n
It will be the fifth grand slam quarter-final of Gauff\u2019s still-fledgling career and her second at Flushing Meadows.<\/p>\n
\u201cI\u2019ve been in this position before,\u201d she added. \u201cAnd\u00a0I think I have confidence in myself that I can go even further.\u201d<\/p>\n
