NEW YORK, NY, USA – The high still hadn’t settled in for the No.48-ranked Anastasija Sevastova when she entered the press room late last night at the US Open.

Just hours earlier, she’d dealt Garbiñe Muguruza the biggest shock of the tournament, outing the No.3 seed and reigning French Open champion in straight sets.

It was definitely the win of Sevastova’s career, and certainly an occasion to celebrate. So did she have any big plans?

“I go to Five Guys maybe, eat a burger,” she answered with no hesitation, before bursting into laughter.

“I don’t know. Maybe have some drinks. My mom is here but she’s leaving tomorrow. It’s her first Grand Slam.”

“And my best friend [is here too]. We’ll maybe go somewhere. They will drink; I will watch.”

Burgers and peanuts seem like a modest plan for a player who’s just scored the win of her career and reached her best result at a Grand Slam in five years, but not for Sevastova.

Sevastova was a rising star back in 2011 when she reached the fourth round of the Australian Open at 20 years old. But injuries soon sapped the desire away from the young Latvian, who hung up her racquets two years later, and was off the tour for two years more.

So while last night’s win over the World No.3 stands as her biggest victory since her return, Sevastova is keen to stay grounded and keep the perspective she gained from her years away from the sport.

“It’s not like it’s my last match. It’s not like it’s over, the tournament,” she mused. “It’s only second round. The third round is in two days. Tomorrow I have to play doubles, so…

“Yeah, it’s a good feeling. We can enjoy it today, but tomorrow is a new day. There are other matches. Nobody thinks about the previous match. You have to think forward. But tonight I can enjoy.”
