Radwanska into semifinals at Nottingham, will play Niculescu

NOTTINGHAM, England (AP) Top-seeded Agnieszka Radwanska kept up her serene progress at the Nottingham Open by beating Lauren Davis in straight sets to reach the semifinals of the Wimbledon warm-up tournament on Friday.

Finding some form after a disappointing first half of the year, the 13th-ranked Radwanska won 6-2, 6-2 for her third straight easy victory in central England this week and will play Monica Niculescu in the last four.

Niculescu, who is unseeded, beat Johanna Konta 6-2, 2-6, 6-2 to end British hopes of a home winner.

Alison Riske of the United States advanced from the quarterfinals after Belgian opponent Yanina Wickmayer retired when losing 6-2, 2-0.

Play was suspended because of rain, with the fourth quarterfinal between Ana Konjuh and Sachia Vickery yet to finish.
