Spieth, McIlroy drop as Sullivan leads in Abu Dhabi

ABU DHABI, United Arab Emirates (AP) -- Jordan Spieth, Rory McIlroy and other big names slid off the leaderboard at the weather-affected Abu Dhabi Championship on Friday, leaving American amateur Bryson DeChambeau to chase clubhouse leader Andy Sullivan in the second round.

After fog delayed the start of play by nearly three hours, Sullivan shot another 5-under 67 to to 10-under and make another strong impression in front of his playing partner, European Ryder Cup captain Darren Clarke.

Spieth and McIlroy were in the marquee afternoon group, but both played erratically and were 1 over after 13 holes when play was suspended for the day because of darkness. Spieth was at 3 under and McIlroy at 5 under.

DeChambeau, the first-round leader, was a shot behind Sullivan after playing nine holes in 1 under.
