I've read a countless number of articles which have mentioned that a player was 'inspired'. Does inspired just mean that a lower ranked player, was determined to beat a higher ranked player, and therefore caused an upset. In what circumstances can this term be correctly used. Could it be said, for example if Nishikori beats Djokovic at the US Open this year (highly unlikely i know) that he was 'inspired'? or because Nishikori is a top 10 player, this cannnot be said. Would Medvedev's victory over Nole be 'inspired'?
