4th set summary - fed gets himself in trouble repeatedly and saves a ton of bps, finally at 4-4 he can't quite dig himself out.
nadal faces 2 bps serving for the match and on one federer had the point basically won and just made a terrible decision when nadal got back into it, hitting a slice overhead instead of resetting for a forehand. nadal gets it on his 2nd mp. 4th set definitely much higher quality than the 3rd.
thoughts overall on the match.. well it was pretty bizarre at times, although not entirely unsurprising. federer largely abandoned attacking the nadal bh for long stretches, and i just can't understand why because it was effective. approaching to the nadal forehand was a debacle that he seemed intent on reliving over and over, and his own forehand deserted him at times mostly in the 3rd set. some terrible approach shots too. as for nadal, he played well towards the end of the 1st set and most of the 2nd, and at times in the 4th (although he got passive in many of the big moments) but apart from that was unspectacular and mostly relied on federer self-destructing, as the match was on feds racquet, as usual..
i don't really see how this win will help nadal in the final, assuming its against djokovic, but also even if murray comes through. nadals backhand really isn't that improved, he doesn't have the uso 2010 serve, and he's still not full of confidence on the big points. his forehand is in great form though, and his movement looks as good as ever.
