Rafael Nadal vs Del Potro !!

It is an epic semifinals clash between two giants!!
Nadal has had a great year so far with !! He has 2 atp 1000 masters and one Grand Slam( Roland Garros ) to his name!! He is currently the number one ATP player in the world and is aimimg for his second Grand Slam of the year and his third US Open!!
Whereas Juan Martin Del Potro is on a comeback to tennis after his wrist injury!! He has been in phenominal form in the US Open! He came back from 2 sets down to win the match in an epic 5 setter match against Thiem!! He then defeated Roger Federer , who was in a great form this year winning 2 Grand Slams and 2 atp 1000 masters!
He beat Roger in 4 sets in a meet after 2009 US Open!
It looks that bith the players are in great form but many will say that Nadal will emerge as the winner after they battle but i think that it will be Del Potro who will win !
Nadal leads the H2H : 8-5 against Del Potro!
Del Potro has come to the semis after tough matches which means that he is ready for a fight and having a 0-2(set) comeback and defeating Roger Federer must have made him really confident!
Nadal on the other hand had a easy draw!
With Del Potro's cannon forehand and Nadal's beyond the baseline play , I think Del Potro will get past Nadal's baseline defence easily! But Del Potro has had 5 setter and a 4 setter match recently so he may have stamina and injury problem ( which i hope does not happen because nothing is worse that losing the match due to those reasons)!!
It is going to be an epic match!
My predictions are that Del Potro will win in 3 straight sets!!
What do you guys think?
