New York, 7 September 2011 | AAP

Samantha Stosur is set to have her patience tested at the US Open this week after rain washed out Tuesday’s play in New York.

With more wet weather forecast for the next two days and officials still to squeeze in men’s fourth-round matches, Stosur is no certainty to get on court on Wednesday (Thursday morning AEST).

Stosur will become Australia’s first woman to reach the US Open semifinals in 27 years if she beats last year’s finalist Vera Zvonareva in their quarterfinal.

The nation’s last female player to reach the final four at Flushing Meadows was Wendy Turnbull in 1984.

The weather forced Stosur to train indoors on Tuesday at the Billie Jean King Tennis Center ahead of her meeting with the Russian world No.2.

The winner of her clash with Zvonareva will take on the victor of Germany’s Angelique Kerber and 26th seed Flavia Pennetta.

Any day of wet weather at the US Open tends to re-ignite debate about the lack of a roof on Arthur Ashe Stadium.

The Australian Open and Wimbledon have retractable roofs and Roland Garros officials plan to follow suit by 2016.

However the prohibitive cost of covering the world’s largest tennis stadium in New York is a factor.

The site is built on landfill with estimates for putting on a roof upwards of USD$150 million (AUD$142 million).

Play was due to resume on Wednesday (Thursday 0100 AEST), weather permitting.
