The 23rd seed Donna Vekic will compete in the fourth round at the US Open for the first time after a commanding 6-4, 6-1 win over Yulia Putintseva in an hour and 19 minutes. The Croat had the upper hand on the court with 28 winners and the same number of errors, leaving Ostapenko on a 13-20 ratio and facing only one break point in the entire match.
Jelena converted it but needed more of those to stay competitive after getting broken four times from nine chances offered to Donna who claimed the opening set with a break in game ten, making three great holds in a row and keeping the pressure on the Latvian who cracked under it.
The Croat was the only player on the court in set number two, earning breaks in games four and six and sealing the deal with a hold at 15 in game seven, advancing into the fourth round for the third time at the previous six Majors.
The 26th seed Julia Goerges toppled the 7th seed Kiki Bertens 6-2, 6-3 in an hour and 17 minutes for the place in the fourth round for the second time in three years in New York. Bertens is yet to find the winning formula at the US Open and today certainly wasn't the day for that, landing 39% of the first serve in to ruin the chances for a more favorable result.
The German had more winners and fewer unforced errors, mixing up her shots nicely and standing strong at the net to take all the momentum away from the rival and score a dominant triumph with four breaks of serve. Finding the range right from the beginning, Julia broke Kiki in games two, four and eight in the opener for a 6-2, with more challenging tennis in set number two where she grabbed a break in game six to move 4-2 up.
Serving for the win at 5-3, Goerges converted the fifth match point after a forehand down the line winner to secure the place in the next round where she will face Vekic. The 13th seed Belinda Bencic had a day off, with Anett Kontaveit giving her a walkover due to viral illness, sending the Swiss into the fourth round for the first time here since 2014 when she played in the quarter-final on debut at the age of 17.
