Seeded no.3, Roger is the defending champion and the hot favorite to win the Australian Open after Novak Djokovic. The Swiss Maestro was in excellent condition during the Hopman Cup as he won all his matches in straight sets when displaying fantastic tennis alongside a great fitness.
Currently ranked no.99, during the last few months Denis has been playing mainly on the Challenger circuit where he has recently won the titles in Chicago and Almaty, but he is struggling at ATP level. Last time that he won a match on the main circuit was back at the beginning of August when he reached the final in Kitzbuhel starting straight from the qualifications.
