Watson played her first senior tournament in March 2009 - the $25k Jersey Open, but lost in the second round to Katie O'Brien.

Watson began 2010 with a wildcard into the $25k event in Sutton, London, where she made the quarterfinals. She immediately flew to the $100k Midland Classic, losing to qualifier and fellow 17-year-old Beatrice Capra in the first round.

On 22 June 2011, Watson played Mathilde Johansson in her first round match in the Wimbledon Championships, winning the opening set before suffering an arm injury in the second set. Johansson then went on to win in three sets. On 25 June 2011, she and her mixed doubles partner Ross Hutchins beat Marcelo Melo and Rennae Stubbs in the mixed doubles.
