On Day 11 at the Sony Ericsson Open, the world No. 134 will face No. 5 Agnieszka Radwanska of Poland.
Radwanska is going deep into tournaments, reaching the quarterfinals at the recent Indian Wells and the quarterfinals of the Australian Open (where she lost to Victoria Azarenka). Williams is playing in her first tournament since the 2011 U.S. Open.
World No. 1 Victoria Azarenka will play for her 27th straight victory when she takes on Marion Bartoli of France.
On the men's side, No. 9 Janko Tipsarevic will face No. 4 Andy Murray, while No. 6 Jo-Wilfried Tsonga takes on No. 2 Rafael Nadal.
