and pretty easy
del potro is good but he lacks mental toughness
I would say he is pretty tough mentally for an 18 year old player.
Del Potro made too many mistakes with his forehand, and wasn't very solid with his backhand either, his best shot.
But we got to see some very nice points, and some impressive shots by Juan.
The match was very even in the first set, but the most experienced player was able to win it and after that the match was over.
