Two Americans exit at the hands of Ostapenko and Wozniacki three setters.

Jelena Ostapenko celebrates her improvements during the third round of the US Open. 

Jelena Ostapenko kept the errors to less than half to come through another three-setter against Bernarda Pera, winning 4-6, 6-3, 6-3 on Court 17 at the US Open Friday. Caroline Wozniacki shined once again, defeating Jennifer Brady quickly in the final set, advancing on a 4-6, 6-3, 6-1 score at Arthur Ashe Stadium.

The former world number one continued her surprising run back at her home away from home, taking down Petra Kvitova in a clash of titans. With a big name out of the way, her facing Brady was a challenge of the powerful American’s forehand. Ostapenko tallied 120 errors in her first two rounds but somehow got through each of the three sets. With her miraculous way of reaching for victory, the 26-year-old didn’t want to do that again and instead earned her way into the second week.

Pera took advantage of Ostapenko’s slow start, taking the first set 6-4. Errors racked up in the double digits for the Latvian, who improved in the second set, winning 6-3. She had a three-game lead in the decider, but it slipped away. She managed to stay ahead of the American to clear her way to the round of 16 in 1 hour and 48 minutes.

Caroline Wozniacki waves to the crowd after dispatching Jennifer Brady from the US Open.

Wozniacki and Brady got into a competition of serves to love, with the American winning the day on two shutouts and a break to love. It was a fast-paced set that slowed down in the second, with neither player getting through a clean service.

The former world number one broke Brady three times, with two at the business end of the second to go for broke in the third. It was there she went on a five-game run before the 28-year-old found a way to dig into her service. Wozniacki made the final blow, smashing three shots for errors by Brady to finish her match in under two hours.
