Britain's Heather Watson and Alexandra Panova of Russia have won the WTA Baku Cup doubles title in Azerbaijan.

Watson, 22, and Panova, 25, earned a 6-2 7-6 (7-3) victory over the third-seeded pairing of Romania's Raluca Olaru and Israel's Shahar Peer.

It is the British number one's fourth WTA title, and her first since 2012.

Two years ago, she won the Stanford Classic and Texas Open doubles titles, both with New Zealand's Marina Erakovic, and the Japan Open singles.

Watson had gone out in the first round of the Baku Cup singles, losing 6-2 3-6 6-0 to France's Kristina Mladenovic.

Her only Grand Slam doubles appearance to date this year was at Wimbledon, where she partnered eventual singles runner-up Eugenie Bouchard, of Canada, as they went out 6-4 7-6 (7-3) in the first round to Australian pair Ashleigh Barty and Casey Dellacqua.
