Radek Stepanek of the Czech Republic will be looking to have a big week at the ATP Masters 1000 event in Key Biscayne Miami which starts today. Stepanek has been struggling with form so far this season but there would be no better time for him to rediscover his best tennis than at the prestigious event in Miami regarded by many as the 5th Grand Slam. Two years ago Stepanek recorded the best win of his career at the ATP Masters series in Rome when he defeated Roger Federer 7-6 7-6 in the Quarter Finals. Stepanek did reach the final of the ATP event in Brisbane, Australia at the start of the year but he lost out to Andy Roddick. Roddick also lost in the final of the ATP Masters 1000 event in Indian Wells California. Stepanek will be hoping that he can have a great run and cause a few upsets in Miami this week.
