Djokovic N. vs Del Potro J. prediction

In 2007-2013 Djokovic met Del Potro in more than 15 direct confrontations and most of this confrontations were on hard surface. Three years ago Del Potro reached top 5 ATP when he won the only match against Djokovic in the semi-finals of the Indian Wells and that moment was the highest performance that he reached. Djokovic had always hard games against Del Potro losing in the last four confrontations at least one set each game. Djokovic had straight wins with 2-0 in every game that he played on Toronto and is possible to be the same way on this competitions but I think that Del Potro will gave him a lots of headache and my prediction for this match is Del Potro will win with an advantage of 4.5 games.
