Watson progresses in Auckland

Heather Watson ensured a winning start for British sport in 2013 by beating 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 today 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.

Agnieszka Radwanska eased through her opening match with a straight-sets victory over Greta Arn.

The Polish top seed came through 6-2 6-2 against the 2011 champion to set up a second-round clash with Simona Halep of Romania.

Second seed Julia Goerges also enjoyed a straightforward win, beating Anastasija Sevastova 6-3 6-4.

Other games today saw sixth-seeded Yaraslava Shvedova see off Lara Arrubarrena-Vecino in straight sets, while eighth seed Mona Barthel was a 6-1 6-3 winner over Grace Min of the United States.

Romina Oprandi dropped only two games in beating Nudinga Luangnam and Marina Erakovic saw off Stephanie Dubois for the loss of three games.
