It just seems that recently he can't seem to close out matches as dominant as before. Against Djokivic he pretty much had the first set in the bag but gave it away. Against Baghdatis he could not close out the match serving at 5-4 (although the heat could have contributed to this). He is letting players back in to matches too easily. Even against Canas earlier he was up a break in the third and gave that away too. Is he mellowing?
