Watson determined to build on narrow Sharapova loss

British teenager Heather Watson says she is "determined and excited for the future" after pushing Maria Sharapova all the way before losing in three "really competitive" sets at the US Open.

Watson adds that the crowd for her 3-6 7-5 6-3 first round defeat by former champion Sharapova was "amazing".

The 19-year-old former junior champion led 6-3 5-5 at one stage in her senior US Open debut.

Sharapova praises Watson's movement around the court but admits she did not do enough to put pressure on the young Briton in the first set.
