Top-seed Iga Swiatek crashed out of US Open, suffering a 6-3, 3-6, 1-6 defeat to world number 21 Jelena Ostapenko in Women's Singles Round of 16. 

Swiatek, who was also the defending champion in the competition, started off well against Ostapenko, winning the first set 6-3 but was outdone by her opponent in the following two sets. Swiatek might have been presumed the favourite given her dominance of the WTA Tour over the last couple of years but on-field it's Ostapenko who has had an edge over the Pole. In fact, before this meeting, Ostapenko had won all three of the pair's previous showdowns.

"I always expect a tough battle against Iga," Ostapenko said on court after her triumph. "She's won many Slams and she plays very consistent. I just went on court and I had to play aggressive because that's what she doesn't really like. In the third set, I stepped more in the court and I was serving better."
