#1 The US Open likes to mess with Djokovic - an advantage for Del Potro?
Believe it or not, Djokovic has only come out as a US Open winner on two occasions in 2011 and 2015.
Sunday will be Djokovic's eighth appearance at a US Open final - winning two of them and having to accept second place for the other five finals.
So if we are talking past records ahead of this final - Djokovic doesn't always perform his best when it really matters.
Maybe something for Del Potro to know in his match preparations.
Djokovic will, of course, need to make sure he puts the past behind him and aim for a third major win in New York.
Records may reveal a lot about a tennis player but at present, the Serb has it in his hands to change all of that.
