The fourth round came to a close on Day 8 of the 2010 Australian Open. Both Serena and Venus Williams progressed, as well as Chinese Li Na and Belorussian Victoria Azarenka.
Top seed Serena Williams routinely defeated home favorite Samantha Stosur 6-4 6-2 in the fourth round. The impressive performance by the American saw her lose only seven points on serve throughout the match, including one double-fault in the second set.
Serena’s opponent in the quarterfinals will be seventh-seeded Victoria Azarenka who won the day’s final match, coming back from a set down to beat Russian Vera Zvonareva 4-6 6-4 6-0 in almost two and a half hours.
Venus Williams had more trouble advancing to the quarterfinals than her sister Serena. The sixth seed lost the first set and was a break down in the second before recovering for a 3-6 6-2 6-1 victory against Italian Francesca Schiavone.
Next for Venus will be seed No.16 Li Na of China who upset fourth seed Caroline Wozniacki 6-4 6-3 to join countrywoman Zheng Jie in the last eight, thus making history for China – it is the first time two Chinese players are in the quarterfinals of a Grand Slam event. Li Na and Venus Williams have had only one career meeting, at the 2008 Beijing Olympics, and the winner was Li.
Other quarterfinal pairs include Justine Henin vs. Nadia Petrova and Zheng Jie vs. Maria Kirilenko.
