Two more seeds were knocked out of the WTA tournament in Birmingham on Tuesday as Tamira Paszek and Urszula Radwanska bowed out in the second round.

Paszek, ranked No.29 in the world and seeded four in the tournament, went down 2-6 6-2 6-3, to American Alison Riske, the 22-year-old 167th ranked player recording perhaps her finest win yet.

“It was the third time I’ve played her and it’s always been on grass, so I’m glad I pulled through,” said Riske.

“I’ve always really enjoyed this tournament. I think it comes down to the fact I really enjoy playing on grass and they do a really great job running this tournament. I feel at home in Birmingham.”

Radwanska, seeded eight, produced a limp display in losing 6-3 6-2 to Donna Vekic of Croatia.

However, home hope Heather Watson, seeded 14, made no mistake in her first round match beating the experienced Hungarian Melinda Czink 6-4 7-6 (7-0).

Italy’s 15th seed Francesca Schiavone almost joined Paszek and Radwanska in exiting early but she fought back from a set down to prevail 2-6 6-3 7-6 (7-3), over Georgian Anna Tatishvili.

Two seeds had been eliminated on Monday when Asian duo Su-Wei Hsieh of Taiwan and Japan’s Ayumi Morita were both beaten in straight sets.
