World No 1's winning streak goes on but Wozniacki loses
Victoria Azarenka extended her 2012 winning streak to 20 matches on Tuesday, but Caroline Wozniacki crashed out of the BNP Paribas Open.
World No 1 Azarenka made short work of Julia Goerges, needing just 63 minutes to post a 6-3 6-1 victory and reach the quarter-finals.
In the quarter-finals she will face Polish fifth seed Agnieszka Radwanska, who led Jamie Hampton 6-3 4-6 3-0 when the American retired hurt.
A recent winner in Dubai, Radwanska is another of the WTA's form players - she has won 20 of her 23 matches this season, only losing to Azarenka - so the Belarusian is expecting a tight battle in the last eight.
Battles
"I think it's going to be a tough match, as usual. We have really tough battles," said Azarenka. "I'm really looking forward to playing her again. She's a great player and a very good challenge for anybody to play."
However, Azarenka's predecessor as world number one, Wozniacki, bowed out to another former top-ranked player, Ana Ivanovic.
Ivanovic stunned Wozniacki by posting a 6-3 6-2 win.
Second seed Maria Sharapova also made light work of her fourth-round match, beating Italy's Roberta Vinci 6-2 6-1, to set up an all-Russian quarter-final against Maria Kirilenko.
Kirilenko beat another Russian, Nadia Petrova, 6-1 5-7 6-2, while there were also wins on Tuesday for Marion Bartoli, French Open champion Li Na and Angelique Kerber.
