Played in the United Kingdom as the only major not in the US, the British Open is being held at Carnoustie Golf Links in Scotland in 2018.
TAB leading contenders: $13 Dustin Johnson; $17 Justin Rose; $18 Rickie Fowler, Rory McIlroy; $21 Jon Rahm, Jordan Spieth, Tommy Fleetwood, Brooks Koepka; $26 Justin Thomas, Tiger Woods, Alex Noren, Sergio Garcia. "They're all great people".
"I generally played better than the score, but I hit a couple bad tee shots on the back nine and had to take drops", he said after slipping from two-under through the turn.
Woods, who returned from his latest back operation at the end of previous year, has blown hot and cold this season but he clearly can not wait to get to grips with Carnoustie for the fourth time in his career.
But although the 14-time major victor visibly winced after hitting his opening tee shot, that appeared to be the result of getting some dust from the dry ground in his eye and he went on to make an ideal start with a birdie from 10 feet.
Spieth carded two birdies in his first four holes of the day and dazzled spectators with a bold putt along the edge of a bunker that set up a par save at the eighth.
Day, Scott and Davis are all five strokes off the pace after signing for even-par 71s in increasing afternoon winds on the Scottish links.
The Open Championship runs from July 19 to July 22. With rain expected in the forecast early Friday, Woods and those around him could again be fighting the elements.
No course is overly long for the powerful Finau, who averaged almost 350 yards off the tee, mostly with irons.
Woods had a bit of an up-and-down round, but finished dead even.
But have you ever slept wrong and awoken with a stiff neck on the first day of the British Open?
"I hadn't seen a weather change like that of all my years on Tour, not like that, not that quickly". "It was an awesome experience", Davis told AAP afterward.
"Speed-wise, [this course is playing] about the same [as when I won at Hoylake in 2006]", said Woods. "I had a nice par save after driving it in the bunker at 6. Back nine obviously wasn't what I was after".
On the longest day - from Sandy Lyle hitting the opening tee shot at 6:35 a.m. and the group including newcomer Bronson Burgoon finishing off the first round almost 13 hours later - everyone had their own style of getting around the course reputed to be the toughest links in golf. A certain shot you think is a wonderful shot down the middle of the fairway could bounce some weird way.
