Still it was very close. In the 1st set leading 3-2 with 2 BPs and 2 second serves and balls sitting in inviting positions to be punished, Andy got a bit tentative and made 2 UEs. Had he won one of the two and then win the 1st set, the match would likely have gone to a 3rd set and anything could have happened.
One thing that surprised me today was that Andy did not target Federer's BH where Nadal got a lot of success in previous matches.
Instead, Andy was going mano u mano with Fed on his lethal FH which I think is a tactical mistake. Fed can generate so much pace off his FH that it puts Andy on the back foot time and time again.
Out of the top 4, I believe Fed's FH is the most lethal.
Yet against Del Portro he was not consistent with his FH, a bit like Andy's BH today
