First round Thursday, 19 July 2018 Kevin Kisner opened with 66 (−5) for a one-shot lead over
Tony Finau,
Zander Lombard, and
Erik van Rooyen. Kisner was one-over after his first five holes before making a 40-foot eagle putt at the 6th. He made another 35-footer for birdie at the following hole, and added three straight birdies on the back-nine. Finau made eight birdies in his round to join Van Rooyen and Lombard in second place. Defending champion
Jordan Spieth was 3-under before playing his final four holes in 4-over, including a double bogey at the 15th. He finished with 72 (+1). Three-time champion
Tiger Woods, playing at the Open for the first time since 2015, had two early birdies but made three bogeys on the back-nine to finish even-par.
Second round Friday, 20 July 2018 Zach Johnson, the
2015 champion, holed a 30-foot putt at the 18th to post a round of 67 (−4) and tie first round leader
Kevin Kisner. Kisner held a two-shot lead playing the 18th, but hit his approach in the burn guarding the green and made double bogey.
Pat Perez,
Tommy Fleetwood and
Xander Schauffele were a shot behind at five-under. Perez was tied for the lead playing the 18th, but hit into a bunker and made bogey. Fleetwood, runner-up at the
U.S. Open after shooting 63 in the final round, shot a bogey-free 65 (−6); Fleetwood owns the course record of 63 at Carnoustie, made at the 2017
Dunhill Links Championship.
Rory McIlroy, the
2014 champion, shot 69 (−2) for a second straight day to join a group two shots out of the lead.
Jordan Spieth, one-over after the first round, rebounded with a 4-under 67 to get within three of the lead, while
Tiger Woods shot another even-par round. World No. 1 and 2
Dustin Johnson and
Justin Thomas both missed the cut, Johnson making a double bogey at the last while Thomas made three straight double bogeys on the front-nine. Spieth, beginning the third round three off the lead, drove the green on the par-four 1st and made eagle, and then added a birdie on the 4th to tie. At the 10th, he hit his tee shot into the rough but managed to escape with a birdie, and then made another at 11. He birdied the par-5 14th, and then holed a long birdie putt at the par-3 16th. Schauffele shot a four-under 67 that included six birdies, finishing his round with a long putt at the 18th from just off the back of the green. Kisner, tied for the lead coming into the round, shot a bogey-free 68 (−3).
Francesco Molinari didn't make a bogey while getting six birdies to shoot 65 (−6) and move to three off of the lead.
Tiger Woods began the round six behind but made three straight birdies on holes 9–11, and then briefly tied for the lead after a birdie at 14. He made bogey on the 16th but managed to save par at the last after his tee shot narrowly missed the burn. He finished with a round of 66 (−5) and was four back.
Zach Johnson was tied with Kisner entering the round but made bogey at 11 and double bogey at the 12th, settling for a one-over round of 72 and falling four shots behind.
Justin Rose had the round of the day with 64, tying for the lowest round at an Open Championship at Carnoustie. Molinari was three shots behind at the start of the round, and began with 13 straight pars before a birdie at the par-5 14th. He hit his approach close to the pin at the 18th, and converted another birdie to post 8-under. Molinari did not make a bogey in his last 37 holes.
Tiger Woods, paired with Molinari, made two birdies on the front-nine to take solo possession of the lead. At the 11th, however, he hit his tee shot in the rough, and did the same with his approach over the green. His chip shot came up short of the green, and he failed to get up-and-down, settling for a double bogey. He made another bogey at the 12th, and despite getting a birdie at the par-5 14th after chipping from close to the 4th pin on the double green, he finished three shots behind after an even-par 71.
Xander Schauffele was in a three-way tie for the lead at the start of the round, but found trouble at the 5th when his approach shot buried in a greenside bunker. That led to a bogey, and he made another bogey at the 6th after hitting into a bunker once again. At the 7th, Schauffele hit his tee shot into the rough and failed to get out on his second shot. His third went over the green, and he made double bogey. He rebounded with a birdie at the 10th to get back into the lead, and another at the 14th. One shot back of Molinari playing the 17th, Schauffele's approach went well right of the green, and he made bogey to finish two behind.
Kevin Kisner was also tied for the lead, but began his round with a double bogey at the 2nd after having to play sideways out of a fairway bunker. He made three more bogeys on the front-nine for a four-over 40. He began the second nine with a birdie at 10, joining a six-way tie for the lead at six-under. A dropped shot at the 12th, however, saw Kisner fall out of the lead, and he also finished two behind Molinari. Defending champion
Jordan Spieth, tied with Kisner and Schauffele at the start of the round, failed to make a birdie on his way to a five-over 76. He made a bogey at the 5th after hitting into a fairway bunker, then had a double bogey at the 6th after taking an unplayable lie from a bush. He made two more bogeys on the back-nine to finish four shots back.
Rory McIlroy was two-over par after his first eight holes, before birdies at the 9th and 11th. At the 14th, he holed a long putt for eagle to tie for the lead at 6-under. However, he failed to make another birdie the rest of the round, and settled into the four-way tie for second.
Justin Rose, who needed a 13-foot birdie at the 18th on Friday just to make the cut, eagled the 14th after his approach hit the flag, then birdied the 18th after another close approach to also finish runner-up.
