I'm still to be fully convinced that Tiger is back. There was no real pressure on him yesterday, so he was able to go out there and shoot what was in fairness to him an incredible round. I don't think there is anything wrong with his swing mechanics anymore, he has done enough "reps" to be comfortable with his new swing. But it all comes down to what is going on between those ears of his.
If you look at the last few tournaments this year which he had a chance to win, first being Abu Dhabi where he never looked like pipping Robert Rock to the post.
Second then was in Pebble Beach where Phil Mickelson just absolutely blew past him and Tiger looked only a shadow of his former self.
Until he can actually go and win a tournament with a "full field", he won't be truly back in my eyes. Despite me being so negative though, it is great to see that he is almost but not quite back to his former best. I think that if it was any player other than Rory going into those final 5 holes with only a two shot lead over Mr Woods, then Tiger would have won last night.
