Heather Watson ensured a winning start for British sport in 2013 by overcoming fifth seed Sorana Cirstea in the first round of the ASB Classic in Auckland.

The 20-year-old played her part in the success story that was 2012 by becoming the first Briton to win a WTA singles title since 1998, and here she won the first set 6-3 before her Romanian opponent was forced to retire because of illness.

The British number one will face Kiki Bertens of Holland in the next round.
