EASTBOURNE, England — Caroline Wozniacki retired three games into her semifinal at the grass-court Nottingham Open Friday, handing 18-year-old Swiss Belinda Bencic a place in the final against former Wimbledon runner-up Agnieszka Radwanska. The second-seeded Wozniacki was 3-0 down when she called for her trainer and stretched her leg muscles before deciding she could not continue. Radwanska beat Sloane Stephens of the United States 6-1, 6-7 (3), 6-2 also Friday to stay in contention for a second title at the Wimbledon warm-up tournament. The ninth-seeded Radwanska clinched the victory on her second match point with a mishit return that crept over the net and beyond the reach of Stephens. Radwanska served for the match at 6-5 in the second set but Stephens broke before dominating the tiebreaker. The Polish player, who won the Eastbourne title in 2008, lost to Serena Williams in the Wimbledon final in 2012. Bencic is bidding for her first title, after losing finals in Tianjin in 2014 and 's-Hertogenbosch this year. Istomin-Querrey final In Nottingham, Sam Querrey of the US, the 12th seed, will face Uzbekistan's Denis Istomin, the world No. 92, in the final of the Wimbledon warm-up tournament in Nottingham after both came through their semifinals Friday. Querrey came from a set down to beat Ukraine's Alexander Dolgopolov 4-6, 6-3, 7-5 after Istomin saw his match against Marcos Baghdatis of Cyprus end prematurely when his opponent retired injured. Baghdatis, the world No. 59, gave up when leading 2-1 in the first set. — Agencies
