BASEL: Roger Federer returns after six weeks off resting and easing into his new role as a father of twin girls when he headlines at his home event, the Swiss Indoors, starting on Monday. The world number one opted out of the recent ATP Asian sojourn after a gruelling mid-season, where he re-established ATP superiority with titles at Paris and Wimbledon plus a US Open final appearance. The St Jakobshalle will miss out on a possible re-run of the US Open final, after ailing New York winner Juan Martin Del Potro withdrew with a lingering wrist injury. The Argentine has not been the same player since he beat Federer for the trophy in September but the Tour continues apace, with Basel, the Paris Masters and the year-end World Tour Finals in London from November 22 to come as the 2009 campaign draws to a close. Federer's record 15 Grand Slam titles will be feted in suitablly high-class style on Monday's opening day, with a ceremony featuring a performance by Spanish soprano Montserrat Caballe. The Catalan opera singer will be accompanied by the Opera Choir of the Theater Basel and the Basel Festival Orchestra, before Federer's opening match against a qualifier. "I've been back practising and training now for some time and all is going well," Federer said in the run-up to the event he has won for the last three years. "I feel much better. I'm looking forward to playing my hometown tournament." Federer made his last appearance on court in a Davis Cup win over Italy the weekend after losing the US Open final. Beijing champion and Shanghai semi-finalist Novak Djokovic makes his debut at the tournament in the main draw as second seed, with German Andreas Beck his first opponent. Chile's Fernando Gonzalez, a familiar face in Basel after taking the 2005 title and two runner-up spots, is seeded third, with a first-round match against American John Isner. Croatian Marin Cilic takes the fourth seeding on a wild card after Del Potro's pullout while Czech Radek Stepanek is seeded fifth ahead of Swiss Stanislas Wawrinka.
