Wozniacki suffers slam setback

TENNIS: Women’s top seed Caroline Wozniacki is an injury doubt for next week’s Australian Open after hurting her wrist in a defeat to Agnieszka Radwanska at the Sydney International. The Dane, who is yet to win her first grand slam title, could now be overtaken as world No1 by Wimbledon champion Petra Kvitova before the major gets underway on Monday.
