GB's Robson and Konta to face Argentina in singles rubbers
Great Britain's Fed Cup Captain Judy Murray named British number one Laura Robson and number three Johanna Konta as her singles players to face Argentina.
With British number two Heather Watson sidelined as she recovers from a bout of glandular fever, Murray selected Robson and Konta to take on the South American team.
Robson and former British number one Anne Keothavong have been confirmed as the doubles team for the middle rubber.
Murray said: “It was a very difficult decision to make. We have some very good options in the team with good strength and depth. Ultimately I based my decision on what I felt was the best match up on clay.
"Jo has been out in America playing on clay for the last four weeks and I felt that her game would be the best match up for tomorrow. We have really enjoyed the time we have spent here so far, but now the real challenge begins tomorrow."
Robson added: "I don’t know much about my opponent, I believe we have played once previously a few years ago. It’s a surface that definitely suits her but I have been practicing really well this week. I am confident in our team’s chances and I think we’ll do really well."
The winning nation will be promoted to the World Group II in 2014.
