Anastasija Sevastota into quarterfinals of the us open 2016

Anastasija Sevastova of Latvia, ranked No. 48 in the world, continues her career run here at the Open, taking out No. 13 seed Johanna Konta of Great Britain 6-4, 7-5 in Arthur Ashe Stadium.

She moves on to the quarters, the first time in her career she's made the final eight of a major. It was the second major upset of the tournament for the Latvian, having also taken out No. 3 seed Garbiñe Muguruza in the second round. 

"It’s so tough to play, after these two matches," said an emotional Sevastova after the match. "I'm just fighting and fighting in my head."

Sevastova is the first Lativan to reach a quarterfinal at a Slam since Larisa Savchenko reached the Wimbledon quarters in 1994. Just as noteworthy, Sevastova had actually retired from tennis back in 2013 due to a slew of injuries, and only unretired at the start of the 2015 season.

"It was hard moments in 2013, I was injured on and off and it was hard to play," Sevastova said. "But now, I’m back."
