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

Showers started Monday night and were expected to continue through midweek.

Only the two main stadiums, Arthur Ashe and Louis Armstrong, could host matches.

They have roofs that can close.

Madison Keys, the No. 22 seed, opened play in Ashe against Alina Korneeva.

In Armstrong, men’s No. 5 seed Flavio Cobolli lost the first set to Francisco Comesana.

Several other players had to wait.

This included No. 2 seed Elena Rybakina, No. 12 Belinda Bencic, and No. 32 Maria Sakkari.

Rybakina has several ways to reach the No. 1 ranking at this tournament.

She was set to face American Thea Frodin, a 17-year-old from California.

Frodin worked as a body double for actor Demi Singleton in the 2021 film "King Richard."

In that film, Singleton played Serena Williams.

Coco Gauff, the 2023 U.S. Open champion, 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.
