Li Na and Agnieszka Radwanska face off at 8 a.m. ET/1 p.m. GMT. If you can't watch the match, listen to the action live online for free as one of these two females will move on to the Wimbledon 2013 semifinals.
For Na, it's a return to the quarterfinals at the All English Club since 2010. For two consecutive years, Na was ousted by the second round of the tournament. Everybody knew she was better than that, but she simply couldn't perform on grass. However, she's back and ready to continue her run for her second grand slam title. Na is a former Australian Open winner and one of the only players remaining in the tournament who has won a slam title.
Radwanska will look to better last year's performance at Wimbledon. The only way she could accomplish that is by becoming the 2013 Wimbledon champion. Radwanska was defeated by Serena Williams in the Women's Singles Finals in 2012. However, the world's No. 1 was bounced in the fourth round, doing every other player a chance since this was Williams' tournament to win.
Na owns the head-to-head battle between the two as she is 6-4 in her career against Radwanska. The two last met at the 2013 Australian Open where Na eliminated Radwanska in the quarterfinals of that tournament.
