Rory McIlroy and Rickie Fowler were part of a five-way tie for the lead at the Abu Dhabi Championship after Andy Sullivan made a triple-bogey in fading light to relinquish a two-shot advantage late in a fog-affected third round Saturday. Sullivan drove into a bush, couldn't find his ball, returned to the tee and eventually made a 7 at No. 9 in a dramatic finish to the day's play, which ended with most of the field yet to finish their third rounds. Sullivan dropped to 9-under and was a shot behind McIlroy, Fowler, Branden Grace, Ian Poulter, and Joost Luiten, who all have holes to play early Sunday before starting the final round. "It's a really bunched leaderboard," said McIlroy, who ended his second round on Saturday morning with a birdie-eagle finish to be tied for second. "It will be a bit of a sprint to the finish." There are 21 players within three shots of the lead — and Jordan Spieth is among them. The top-ranked American started the third round seven shots back and finished it in the gathering gloom and in a six-ball — a career-first — after barely beating the horn on the 9th tee. Indeed, the claxon sounded at the top of his backswing as he rushed to avoid an early morning return Sunday. Spieth is three shots back after a 4-under 68, and in need of what he called a "crazy round" to take victory in his first regular European Tour event. Sullivan is one of five players a shot behind — with 2012 champion Robert Rock, Henrik Stenson, Thomas Pieters, and Rafael Cabrera-Bello — after his nightmare on his ninth hole, when he went way right off the tee. He searched for his ball in two separate bushes — McIlroy even came to help him — but had to reload. Sullivan's second drive found the rough on the right, his approach was short, his chip onto the green poor, and he two-putted from 10 feet. McIlroy chased down Sullivan in the final round of the season-ending World Tour Championship in November, to clinch the Race to Dubai title. This time, it has happened earlier — and it was Sullivan who imploded. The other member of the final group was Bryson DeChambeau, the American amateur with the self-styled nickname of "The Golf Scientist," who plays with a set of home-made clubs that are all the same length. He started the third round tied on 8-under par with McIlroy, but dropped back to 7 under by the time play was suspended. The group still had nine holes to play. DeChambeau removed his earphones, took off his flat cap, and approached McIlroy on the practice green ahead of his first round with the four-time major winner. "I'm Bryson, nice to meet you," DeChambeau said. And in another display of reverence, the US Amateur and NCAA champion applauded when McIlroy's name was announced on the first tee. DeChambeau was about to learn just how much pressure is involved in contending in a top-class field at a high-profile professional event. He drove into the bunker on No. 1, then drove into the tree on the right on No. 2 to make bogey. Fowler shot 68 in the second round and continued that form by picking up three birdies in the 10 holes he managed in the third round. Poulter, playing with a taped-up thumb that he "took a chunk out of" Thursday, made four birdies in five holes around the turn and was 5-under after 13 holes of his third round. Play started nearly three hours late — for the second straight day — because of thick morning fog. Resuming on No. 14, McIlroy made three straight pars, to take his number for the round to 15, before landing approach shots inside two feet on Nos. 17 and 18. He nearly holed a wedge shot on No. 17, before hitting a 5-wood from 268 yards to 18 inches on the last. He tapped in his eagle putt for a 70. Dufner in sole lead Jason Dufner fired a seven-under-par 65 to grab the outright lead after the second round of the CareerBuilder Challenge in La Quinta, California Friday. Dufner began the day in a four-way tie at the top but came out firing in round two, showing flashes of the form that won him his only major, the 2013 PGA Championship. Dufner began with a pair of birdies, bagged another at the fifth, and closed his opening nine with a run of three straight to reach the turn at six-under 30. His only bogey came at the 10th but he carded two more birdies at 12 and 14 to post a 15-under total of 129. One stroke back at 130 was fellow American Jamie Lovemark, who matched Dufner's 65 thanks to an early birthday gift at the first, his 10th hole of the day, where he holed out from the fairway on the Nicklaus Tournament Course for an eagle-two. Five players were bunched at 12-under, three shots off the pace, including India's Anirban Lahiri (68), Canadian Adam Hadwin (66) and Americans Jason Gore (64), Andrew Loupe (66) and defending champion Bill Haas (66). Another stroke back was five-times major winner Phil Mickelson, who returned a 65 and said that despite a belated start to his season he was nearing top form. — Agencies
