"If the wind stays like it is, it's really not too difficult," Hamilton said. "If you can take advantage of the par-5s and throw some other birdies in, and stay away from the high numbers, I think somebody is going to shoot a good score."
Then there was Lloyd Saltman, a 27-year-old Scotsman who competes on the European Tour.
Playing in the first group of the day with Peter Senior and Oliver Fisher, Saltman sent his opening tee shot into a compound of hospitality tents far right of the fairway. He immediately reached for another ball, teed it up again, and knocked another one out of bounds. Finally, with his third attempt and taking what was officially his fifth shot of the hole, he got one in the fairway. He wound up taking a quadruple-bogey 8 and finished with a 79.
Saltman wasn't the only one who had trouble at No. 1. Promising young American Brooks Koepka also opened with an 8. Bud Cauley and Chris Wood both walked away with 7s.
Tiger Woods is the overwhelming favorite, as always. But the world's top-ranked player is mired in the longest drought of his career in golf's premier events, a stretch of 20 tournaments going back to the 2008 U.S. Open.
"I feel very good about my game," said Woods, who had an afternoon tee time. "Even though I haven't won a major championship in five years, I've been there in a bunch of them where I've had chances. I just need to keep putting myself there and eventually I'll get some."
When Woods won his 14th major at Torrey Pines more than five years ago, he seemed a lock to break Jack Nicklaus' record of 18.
Now, it's not so certain.
A messy divorce, injuries and a swing change have chipped away at Woods' dominance. He's still the best player in the world, with four victories already this year on the PGA Tour, but he hasn't been able to finish the job on the biggest stages.
"The self-belief you have to have, maybe there's a little dent in there," said three-time Open champion Nick Faldo. "He hits the wrong shot at the wrong time, where before Tiger would hit the right shot at the right time."
