美国《商业周刊》在今天的一篇文章里说 The Australian Open winner has beaten "King of Clay" Nadal in clay court finals in the most recent events the pair played. If he defeats Nadal at Roland Garros, the sky's the limit for new global endorsement deals. Djokovic's current endorsement commitments, with the likes of Head and Sergio Tacchini, are thought to net him close to $11 million annually. So far in 2011, on the court, Djokovic has earned about $5.5 million in prize money, blowing away Nadal ($2.7 million) and Federer ($1.4 million).
