Groth knocked out in Miami
Jarmilla Groth exits the Miami Masters after going down 7-6 (7-4) 6-2 to Russian third seed Vera Zvonareva.
Samantha Stosur is the last Australian standing at the Miami Masters after Jarmila Groth fell in the third round.
Groth, ranked a career-high No.30 in the world, went down 7-6 (7-4) 6-2 to Russian third seed Vera Zvonareva on Sunday.
Fourth seed Stosur meets former world No.1 Maria Sharapova in the fourth round on Monday. (Tuesday AEDT).
Meanwhile, second seed Kim Clijsters, the winner of the last two grand slams, notched her 500th career win when she beat tricky Spanish left-hander Maria Martinez Sanchez 4-6 6-4 6-3 in their third round match up.
Clijsters said that while the shoulder injury which forced her to pull out from a match in Indian Wells was improving, it takes a lot of physio work.
“I have to focus a lot of my attention and my time on my shoulder. But if I can do that it will stay stable,” she said. “That’s obviously what I’m hoping for.”
In the men’s event, former US Open champion Juan Martin del Potro stormed further down his comeback path, the unseeded Argentinian stunning fourth seed Robin Soderling 6-3 6-2.
Del Potro, who beat Roger Federer for the 2009 US Open crown but then missed eight months in 2010 as he recovered from wrist surgery, thrilled his fans at Crandon Park as he beat one of ATP’s standouts to reach the fourth round.
No one had won more matches this year than Sweden’s Soderling, who has claimed 20 matches and three titles.
But now Del Potro has pulled alongside him as he produced his 20th win of 2011.
Del Potro, ranked 51st but climbing fast, has won five of his last seven matches against top-four players and has now beaten Soderling in their past three encounters.
Spain’s David Ferrer, the world number six, also produced a third-round victory as he defeated Indian Somdev Devvarman 6-4 6-2. Mardy Fish kept the US flag flying as he defeated Frenchman Richard Gasquet 6-4 6-3.
“It’s very important to sort of stay the course against someone like him, try to neutralise his best shot, which is his backhand crosscourt, and then try to take your shots from there,” said Fish, who next faces del Potro.
Polish number nine Agnieszka Radwanska defeated Russian Maria Kirilenko 7-6 (7-2) 6-3, while 15th seed Marion Bartoli of France, an Indian Wells finalist, beat Ekaterina Makarova of 6-0 6-2.
Serbian 2008 Roland Garros champion and one-time world number one Ana Ivanovic advanced as Frenchwoman Virginie Razzano retired from their match with a left thigh injury trailing 2-6 6-2 3-0.
Meanwhile, French Open champion Francesca Schiavone beat Lourdes Dominguez Lino 6-4 7-6 (7-2) and eighth seed Victoria Azarenka of Belarus defeated Dominika Cibulkova 3-6 6-3 6-4.
