In the third round Elina defeated American Shelby Rogers in straight sets: 6-4 7-5. 

In an equal first set Elina managed to break in the tenth game to finish the opener in her favor. In the second set Rogers took an early lead with a break (2-0), but Elina immediately broke back and won the next four games. In the eighth game Elina failed to serve out the match, while Rogers saved three matchpoints. Nevertheless, Elina was able to win another game on the American's service to finish the match before tie-break. 

"First of all, I want to congratulate Shelby, she showed amazing tennis and fought untill the end," Elina said after the match. "Also her last match was incredible, so well done for her. I tried to wait for my moment, take advantage of my chances. I was very, very lucky on the last point, probably it is just my day (smiling). I worked hard to get to this stage of the tournament, it's incredible that it all happened. This season I went through a lot of tough matches and, I hope, I will continue to show my best tennis". 

For the spot in her maiden quarterfinal in New York (and the third at Slams), Elina will face a winner of the match between Elena Vesnina and Madison Keys.
