NEW YORK, NY, USA -- One day after the all-American women's singles final, another all-American final took place -- and again, one player was able to swiftly ease to the trophy.

In the 2017 US Open girls' singles championship match, 16-year-old Amanda Anisimova, the No.4 seed, dispatched her compatriot, 13-year-old wild card Cori Gauff, 6-0, 6-2, in 65 minutes.

This is Anisimova's first junior Grand Slam singles title, besting her runner-up finish at the 2016 French Open. Anisimova has also already made waves with her singles career at the senior level, as she is currently ranked World No.182 and made her senior Grand Slam main draw debut at this year's French Open. 

"I was preparing a lot for [this tournament]," Anisimova said after the match. "After a tough loss in the [women's singles] qualies, I definitely wanted to achieve something big. This is just amazing, and I'm so happy that I won the title."

It was a brisk opening set by the No.4 seed, as she hit nine winners and only eight unforced errors, and never faced a break point.  By contrast, Gauff started slowly, hitting only three winners to her nine unforced errors.

Gauff put up more stern resistance in the second set, having four chances to break the Anisimova serve, and breaking once. But the greater experience of the 16-year-old, at multiple levels, precluded her from faltering at any point in the match.

"I usually feel like the younger one, but I didn't really feel like that today. She's my height, so I didn't feel like that."

- 16-year-old Amanda Anisimova on 13-year-old Cori Gauff.

While both players had 19 unforced errors in the second set, Anisimova had 11 winners to Gauff's nine, and held a whopping 13 break points in the set, converting four. A forehand error by Gauff gave Anisimova the victory, and her first junior Grand Slam singles title.

Anisimova, who says junior Fed Cup this year will be her last event on the circuit, now has her eyes toward the professional ranks.

"My first goal is maybe finish in the top 150 this year. That's what I want to start off with. I'm not going to get too ahead of myself," she said. "I'm just going to one tournament at a time, and just see how they go. I just really want to play in some main draw tournaments at slams. That would be my goal for next year."

Meanwhile, the doubles championship was also decided in straight sets, as the No.1-seeded team of Olga Danilovic of Serbia and Marta Kostyuk of Ukraine defeated Lea Boskovic of Croatia and Wang Xiyu of China, 6-1, 7-5.

This is the third junior Grand Slam doubles title for Danilovic, after triumphing at last year's French Open and this year's Wimbledon. But this is her first Slam victory partnering Kostyuk, who won the girls' singles title at the Australian Open this year.
