Rain stopped play at the U.S. Open on Tuesday.

Rain began Monday night.

It was expected to continue until midweek.

Only two stadiums could host matches.

They are Arthur Ashe and Louis Armstrong.

These stadiums have retractable roofs.

Madison Keys is the No. 22 seed.

She opened play in Ashe against Alina Korneeva.

In Armstrong, Flavio Cobolli is the men's No. 5 seed.

He lost the first set to Francisco Comesana.

Other players had to wait.

They include No. 2 seed Elena Rybakina.

They also include No. 12 Belinda Bencic.

And they include No. 32 Maria Sakkari.

Rybakina has many ways to become No. 1 at this tournament.

She was set to play American Thea Frodin.

Frodin is 17 years old and from California.

Frodin was a body double for actor Demi Singleton.

This was in the 2021 film "King Richard."

In that film, Singleton played Serena Williams.

Coco Gauff won the U.S. Open in 2023.

No. 17 Alex Eala and men's No. 1 seed Alexander Zverev were set to play at night.

This was the third and final day of the first round.
