Women's top seed Karolína Plíšková recorded a straight-sets win on the first day of the US Open, as the second Grand Slam tennis tournament of the year got underway in New York.

The Czech player got proceedings started on the Arthur Ashe Stadium court at Flushing Meadows, and recorded a convincing 6-4, 6-0 win over Ukraine's Anhelina Kalinina.

It was a good day for female Czech players with Plíšková's compatriot Petra Kvitova, the sixth seed, overcoming Romania's Irina-Camelia Begu 6-3, 6-2.

Other women's seeds to win included Germany's Angelique Kerber, the 17th seed, who beat Australia's Ajla Tomljanović 6-4, 6-4, 12th seed Markéta Vondroušová of the Czech Republic who overcame Belgium's Greet Minnen 6-1, 6-4 and 31st seed Anastasija Sevastova of Latvia who battled to victory against 16-year-old American Cori Gauff 6-3, 5-7, 6-4.

On the men's side, fifth seed Alexander Zverev from Germany beat South Africa's Kevin Anderson 7-6, 5-7, 6-3, 7-5 in the second match of the day on the main court.

Fourth seed Stefanos Tsitsipas of Greece recorded a comfortable win on day one as he lost just four games to beat Spain's Albert Ramos-Viñolas 6-2, 6-1, 6-1.

There was one upset on the men's side as ninth seed Diego Schwartzman of Argentina crashed out despite leading by two sets to love against Britain's Cameron Norrie.

Schwartzman took the first two sets 6-3, 6-4 before Norrie replied by taking the next two 6-2, 6-1 and then the decider 7-5.

The night session on the opening day is set to feature men's top seed Novak Djokovic of Serbia against Bosnia and Herzegovina's Damir Džumhur and women's fourth seed Naomi Osaka against her Japanese compatriot Misaki Doi.

Osaka is set to compete despite pulling out of the final of the Cincinnati Masters on August 29 with a hamstring injury.

The tournament is being played behind closed doors due to the coronavirus pandemic and is missing a host of big names on both the men's and women's sides, with several players opting not to travel to the United States because of the health situation in the country.
