US Open Tennis 2020 Results: Thursday's Singles Bracket Winners, Scores, Stats

Sofia Kenin extended her undefeated streak at Grand Slams in 2020 with an easy second-round victory Thursday at the 2020 US Open. 

The No. 2 seed has lost just two sets in nine matches in New York and at the Australian Open after seeing off the challenge of Leylah Fernandez (6-4, 6-3). But the 21-year-old will likely face a tougher test in the third round against No. 27 Ons Jabeur.

The Tunisian was one of six seeded players in the women's draw to advance to the third round. 

Two of the seeded women needed three sets to advance, while No. 10 Garbine Muguruza suffered the most notable upset. 

On the men's side, Dominic Thiem and Andrey Rublev cruised to straight-set wins, while five other seeded players progressed to the next round as well. 

Top Men's Results

No. 2 Dominic Thiem def. Sumit Nagal, 6-3, 6-3, 6-2

No. 8 Roberto Batista Agut def. Miomir Kecmanovic, 6-3, 3-6, 6-3, 6-4

No. 10 Andrey Rublev def. Gregoire Barrere, 6-2, 6-4, 7-6 (7-4)

No. 11 Karen Khachanov def. Andrey Kuznetsov, 6-3, 6-4, 6-1

No. 21 Alex de Minaur def. Richard Gasquet, 6-4, 6-3, 6-7 (6-8), 7-5

No. 31 Marin Cilic def. Norbert Gombos, 6-3, 1-6, 7-6 (7-2), 7-5

Thiem cruised to his second victory in New York with an eighth win of the season in a Grand Slam.

The Australian Open finalist's path to a potential title has been much easier than his start in Melbourne in January. He needed five sets to reach the third round in the season's first major.

However, the road becomes more difficult from here on out. Next, Thiem will face Marin Cilic, who is one of three previous Grand Slam champions in the men's field. 

Meanwhile, Rublev controlled the first two sets against Gregoire Barrere and outlasted his opponent in a third-set tiebreak. 

The 10th-seeded Russian produced 13 aces and won 81 percent of his first-serve points. He also had 36 winners compared to 23 unforced errors. 

Rublev should have an easier path to the fourth round since he is line to face the unseeded Salvatore Caruso, who beat Ernesto Escobedo 3-6, 6-4, 6-3, 6-4.

Roberto Bautista Agut, Alex de Minaur and Cilic were the only seeded men to drop a set, but each prevailed in four sets.

Top Women's Results

No. 2 Sofia Kenin def. Leylah Fernandez, 6-4, 6-3

Tsvetana Pirokova def. No. 10 Garbine Muguruza, 7-5, 6-3

No. 15 Maria Sakkari def. Bernanda Pera, 2-6, 6-3, 6-2

No. 18 Donna Vekic def. Patricia Tig, 6-2, 6-1 

No. 20 Karolina Muchova def. Anna Kalinskaya, 6-3, 7-6 (7-4)

No. 22 Amanda Anisimova def. Katrina Scott, 4-6, 6-4, 6-1

No. 27 Ons Jabeur def. Kaia Kanepi, 7-6 (10-8), 6-0

Kenin has been fantastic in her first two victories. 

The highest seed remaining in the women's draw needed one hour and 21 minutes to dispatch Fernandez. 

Kenin converted on 78 percent of her first-serve points and was accurate on her second serve by winning seven of 11 of those points. 

Next up for the No. 2 seed is a potentially tricky matchup with Jabeur, who survived a first-set tiebreak against Kaia Kanepi before sweeping the second set to claim victory.

The most impressive result of the afternoon came from No. 22 Amanda Anisimova, who overcame a disappointing first set to down fellow American teenager Katrina Scott.

The 19-year-old American committed 48 unforced errors and converted on 41 percent of receiving points, but she rallied back in the second and third sets to remain in the tournament. 

The one upset that did happen came from Tsvetana Pironkova, who stunned two-time Grand Slam champion Muguruza 7-5, 6-3.
