Kenin was seeded 14th.
She had never been past the fourth round of a major tournament until now.

The Australian Open final between two-time major winner Garbiñe Muguruza and 14th-seeded Sofia Kenin has started under a closed roof on Rod Laver Arena following a cool, rainy afternoon in Melbourne.
Former No. 1-ranked Muguruza is unseeded at the tournament but has won majors at the French Open and Wimbledon and is aiming for her first Grand Slam title on a hard court.
The 21-year-old Kenin is into a major final for the first time and was serving first. Until her breakthrough run at Melbourne Park, she'd never gone past the fourth round at a Grand Slam tournament. She beat top-ranked Ash Barty in the semifinals to ensure Australia's long title drought at the season's first major continued.
The junior women's champion at the Australian Open admits she has split nationalities — Andorra and Spain. But her allegiance is firmly with Andorra, one of the smallest states in Europe.
Victoria Jimenez Kasintseva came from a set down to beat Weronika Baszak of Poland 5-7, 6-2, 6-2 in the final at Melbourne Park.
The 14-year-old Kasintseva said she picked up her first racket at the age of 3 and began playing on court with her dad, who has a small tennis academy, at the age of six.
She said she frequently travels between Andorra and Spain, where the academy is located.
Andorra is a small independent European principality situated among the southern peaks of the Pyrenees Mountains and bounded by France to the north and east and by Spain to the south and west.
"I only represent Andorra. Yeah, I live in between them two," she said.
In the meantime she will return to her school studies while juggling her promising tennis career.
"Well, I'm going to do preseason now, like one month of studying, a lot of physical preparation," she said. "Obviously I'm going to try to improve my shots. Then I'm going to play my first tournament, it's a 15K ($15,000 tournament) in March, I think in France."
