Video - Errani's underarm servce on match point

Italy eliminated Poland from the Billie Jean King Cup thanks to a decisive doubles win by Sara Errani and Jasmine Paolini over Iga Swiatek and Katarzyna Kawa.

On match point, Errani made a bold underarm serve. She was rewarded with the winning point and the match victory.

Asked about this in the press conference, the Italian explained: "It's happened a lot this year. I had a good feeling about it, and I did it.

I just advised Jasmine after the first serve, and then I did it, without thinking too much." Qualified for the final, the Italians will play either Slovakia or Great Britain on Wednesday.
