Overall, looks like first round scores are just about right for an Open with the leader at 3 to 4 under par.
Stuary Appleby is due for a major and this could be his week. He's not someone to take lightly up there.
Tiger has 2 doubles so far to go along with 3 birdies through 15 holes. He's definitely within striking distance, which was certainly his goal coming off such a long lay off.
Lefty has had a very Mickelson-like day so far with 4 bogeys and 3 birdies through 14, including two birdies in a row. I like his chances if he stays around even the first round and get to about 2 under after tomorrow.
My dark horse to look out for - Andres Romero. If he can stay out of his own way, I think he could be a real threat to win this thing.
