After a week and a half of play on the historic lawns of Wimbledon, the field has been whittled down to just four women. These four women look to cut the field in half once more.
The first match of the day pits two well-rounded players in No. 8 Angelique Kerber of Germany and No. 3 Agnieszka Radwanska of Poland.
Kerber is the highest-ranked German woman since Steffi Graf, and Radwanska is the first Polish semifinalist since the 1930s.
The two women have split their four career matches, with Kerber winning in their only Grand Slam meeting at last year's U.S. Open. Radwanska laughed last when they met in Japan last year.
One of these women will reach their first-ever Grand Slam final. Who will it be? Stay tuned all morning for up-to-the-second updates and analysis.
