I'd say he's at about 70%. He'll need to be at 75% to beat Dj. Nadal served for the 2nd set in the MC Final, so obviously a very minor fraction of improvement is required to take it to 3 sets, and to win the match I'd say a 5% improvement. Then again, maybe Nadal doesn't even need to improve. We've seen how up and down Dj is. Nadal's groundstrokes looked excellent in the 2nd set, but his serve lately has been way off. He's getting a high% of serves in but isn't doing much with it. Serve might be the area that will put him over the top.
