Nadal looks vunerable. Things just aren't clicking for him. His serve, his groundstrokes, returning big serves, failing to convert BP's - he really is struggling to gain any momentum or rhythm in any part of his game.
Credit to Petzschner, he played the game of his life and was smashing aces and winners at will at times. Nadal is just so hard to beat over 5 sets. I hope Nadal wasn't feigning injuries to refocus himself though.
Enough grit by Nadal to get through the match and finish it well but if he played Soderling tonight he'd have lost in straight sets. Needs to find form - and find it fast and even if he does i don't know if he'll have enough in the tank to go all the way.
