Laura Robson is 25 years old. She is ranked 511 in the world and has not played a competitive match for eight months. Until today. Robson made the trip from Bath, where she had commentated with me on the final rubber of Britain’s run to the Fed Cup World Group 2 play-offs, to Shrewsbury, home of an exceptionally well-run but modest ‘futures’ event for young players trying to make their mark, cobble a living together or come back from injury.
