For 2011, Robson hired a new coach, Frenchman Patrick Mouratoglou, and moved her working base to Paris. Her season was disrupted by injury at the Hopman Cup and she did not compete in a tournament until March 2011; her comeback was then delayed for a further month by an injury in her second competition. Returning again at the end of April 2011, Robson's best performance to date came at the $50k tournament at Indian Harbor Beach, Florida, where she reached the semifinals. Robson split from Mouratoglou just before Wimbledon. She then won her first match at a Grand Slam tournament as she defeated Angelique Kerber, but lost to Maria Sharapova in the second round.
