Donna Vekic heads Julia Goerges to reach the quarterfinals of the US Open

NEW YORK: Croatia Donna Vekic hit Julia Goerges from Germany 6-7 (5), 7-5, 6-3 in Louis Armstrong Stadium to reach it first United States Open quarterfinals after saving a match point in the second set.

Vekic, who is seeded in 23rd place, is playing in the second week of a Grand Slam for the first time and secured his first victory against Goerges, who has defeated her on three previous occasions.

I don't even know how I won this game, Vekic said in an interview on the court. I was just trying to come back ... I kept fighting and believing I could win.

The next one for the 23-year-old Croatian is Swiss Belinda Bencic , who earlier on Monday bothered the world’s number one defending champion Naomi Osaka from Japan

Georges's strong serve, number 26, led her to an early 4-1 lead in the first set, but Vekic broke to a tiebreaker, the first played between the couple.

With 5-5, Georges hit a right-wing winner on the line and took the set into service with another right on the open court.

Goerges broke Vekic at the beginning of the second and had the opportunity to serve the game in 5-4, but the nerves overcame it.

She served three double faults, failed to convert a match point and won a time infraction for serving too slow when Vekic broke down and leveled the match.

Goerges had trouble maintaining the service early in the third, and finally broke in the fourth game. Vekic maintained his leadership and served for the match with 5-4.

A pair of strong returns, a right-wing winner and a stab volley put Goerges at a distance of 15-40.

But that advantage was canceled by a series of right-wing errors, which allowed Vekic to decline again. The Croatian then followed up with a right winner to reach the match point.

Goerges hit two deep shots, putting Vekic on the defensive and forcing her to open a relatively short balloon that Goerges hit a lot. The German defied the call, but Hawkeye confirmed that the ball was out giving Vekic the victory.

The Croatian met for the last time with Bencic, who is seeded 13th, at the French Open this year, where he easily won 6-4, 6-1.
