Fighting spirit fuels Heather Watson's Miami comeback

Britain's Heather Watson says fighting spirit and family support helped her recover from 5-0 down in the final set of the Sony Ericsson Open first round to beat Sorana Cirstea in Miami.

Watson won the deciding tie-break to beat the world number 48 and will now meet 27th seed Lucie Safarova in the second round.

The 19-year-old wildcard from Guernsey explains how she had felt held back by an ankle injury, but is finally playing "care-free".
