Venus Williams will face a surprise opponent in her US Open start after Paula Badosa quit the US Open and ended her season due to injury.

The No. 47 Spaniard’s decision means that Badoa’s season is over due to a back problem she suffered last month at Wimbledon.

The 42-year-old Williams will now start with either a qualifier or a lucky loser in the showpiece Tuesday night match at Ashe stadium..

Badosa explained her decision on social media.

“After struggling for many months to compete again, I am ending my season,” she wrote on Twitter. 

“Those of you who know me know how much I like to compete and how difficult it has been to make this decision. 

“We have tried everything together with my team but the pain is not letting me move forward.”
