Four players, four countries.

That's the singles semifinal field for the U.S. Tennis Association's Women's Circuit $10,000 clay-court Kingsmill Resort Tennis Classic.

Caroline Doyle, a rising 11th-grade left-hander from San Francisco, is the last American remaining. Beginning the week in the qualifying bracket, she beat Arizona State standout Jacqueline Cako, the No. 6 seed, 6-4, 6-3 a day after eliminating top-seeded Alexis King in two tiebreakers.

Doyle's semifinal foe will be No. 5 seed Nika Kukharchuk of Russia, who bounced former Iowa Hawkeyes standout Sonja Molnar 6-4, 6-3. (Kukharchuk is pictured on the blog.)

No. 7 Daiana Negreanu of Romania, handling the 90-degree-plus heat well, rallied past rising 12th-grader Denise Starr of Staten Island, N.Y., 3-6, 6-4, 6-0 to earn a spot against Serbia's Vojislava Lukic, who beat No. 2 seed Anastasia Kharchenko of Ukraine 6-3, 6-2.

Saturday's card will begin at 9 a.m. with Negreanu against Lukic, followed by Doyle versus Kukharchuk.

At least two more countries will be represented in the doubles final, thanks to top-seeded Laura Deigman of Great Britain and Julia Moriarty of Ireland. They edged Americans Erin Clark and Elyse Steiner 4-6, 6-4, 1-0 (10-6).

The other doubles semifinal will be held Saturday, no earlier than noon. Negreanu and Yasmine Guimaraes of Brazil will meet the second-seeded tandem of Cako and Whitney Jones.

Both finals are Sunday; admission is free.
