Sarah Borwell has expressed her delight after being called up to Britain's Fed Cup team as a doubles specialist.

The Teessider, 29, has won four ITF doubles titles this year - two with American partner Courtney Nagle - and joins Anne Keothavong, Elena Baltacha and Mel South in facing Estonia.

She told the Evening Gazette: "I'm so excited. I've been working hard to book my place as the doubles specialist."
