Rory McIlroy vows to keep playing aggressively as he tries to reel in Open Championship leader Kevin Kisner
American Kevin Kisner took the first step towards joining his housemates as a major champion as Rory McIlroy made an encouraging start to the 147th Open Championship at Carnoustie.
Kisner, who led by a shot after 54 holes of last year's US PGA before finishing seventh, carded a five-under-par 66 to secure a one-shot lead over compatriot Tony Finau and the South African pair of Erik van Rooyen and Zander Lombard.
McIlroy, who is seeking a first major title since 2014, was part of a large group on two under par which also included Spain's Jon Rahm, world number two Justin Thomas, 2015 winner Zach Johnson and the English pair of Danny Willett and Matthew Southgate.
Tiger Woods had arrived at the course with Kinesio Tape visible on the back of his neck, a worrying sign given the 42-year-old's litany of injury problems in recent seasons.
But although the 14-time major winner 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.
Woods, who has not won a major since the 2008 US Open, also birdied the fourth and followed a bogey on the 10th with another birdie from 35 feet on the next, but dropped shots on the 13th and 15th and had to settle for a level-par 71.
"I thought I played a pretty solid round and unfortunately didn't take care of both par fives and hit (an) eight iron to both of them," said Woods, who described his stiff neck as "no big deal."
"The round could certainly have been a little better," he added.
Kisner is sharing accommodation with defending champion Jordan Spieth, Thomas, Jason Dufner, Johnson, Jimmy Walker - with eight major titles between them - and Rickie Fowler, with only Fowler and Kisner still seeking their first major success.
But while Spieth slipped from three under to one over by dropping four shots in the last four holes, including a trip into the Barry Burn on 18, Kisner had no such problems thanks to an eagle, four birdies and a solitary bogey.
"It's not intimidating at all," Kisner, who also shared Spieth's plane home after his victory at Royal Birkdale last year, said of his housemates. "They're all great people. That's the best part about it."
Van Rooyen, who failed to convert a four-shot lead after 54 holes of the Irish Open a fortnight ago, carded five birdies and dropped his only shot of the day on the tough closing hole.
"It was playing as easy as it was going to play this whole week this morning, no wind at all, so you had to go out and take advantage of it," said Van Rooyen.
"I was obviously a little nervous, you know, but that's natural. I'm really proud of how I handled it."
McIlroy hit just four of 15 fairways but pledged to continue taking an aggressive approach in pursuit of his second Claret Jug.
"I didn't see the fairway much but as long as you don't hit it in the fairway
bunkers you're always going to have a shot at the green," the 29-year-old Northern Irishman said.
"It wasn't pretty off the tee but I got it done and I took advantage of some unfortunate bounces. I would have taken 69 to start the day."
McIlroy heads the Irish challenge with Paul Dunne next best on level par. Offaly's Shane Lowry is +3.
Former Open Championship winners Padraig Harrington and Darren Clarke have endured tough first rounds. Harrington, who won here in 2007, double-bogeyed the last for a +5 total while Clarke is 11 over after an 82.
