French former doubles specialist Fabrice Santoro on Wednesday temporarily ruled out becoming his country's Davis Cup team captain. Santoro, who holds several ATP records but never won a Grand Slam singles tournament, has been touted as a successor to Guy Forget, who will quit the post next year after what will be his 14th campaign in charge. The retired 39-year-old from Tahiti maintains he is determined to follow a career in radio. However Santoro also believes his familiarity with fellow compatriots would diminish his authority. "It's not a position I would be interested in at the moment," Santoro said on Wednesday at the Etoiles du Sport event which brings top athletes together with the public and future athletes. "When I finished my career I really wanted to pursue a job in the media because I've always wanted to do radio." Santoro said he would not rule out the job if offered it in the future, but added: "I've played with all the guys who represent France in doubles competition. That familiarity would significantly reduce my authority and that's not something that would appeal to me. "But I know that one day I would like to be the captain. Just not now." Santoro's best Grand Slam result in singles was a quarter-final appearance at the 2006 Australian Open. Known for his superb shot-making as much as for his longevity, Santoro is the only man to have appeared in Grand Slam singles competitions in four different decades, from the 1989 French Open to the 2010 Australian Open. His only Grand Slam doubles triumphs came at the Australian Open in 2003 and 2004, while he was a doubles finalist at the US Open in 2003, the French Open in 2004 and Wimbledon in 2006. Forget, meanwhile, will become the event director of the Paris-Bercy Masters when he quits his job as Davis Cup captain next year.
