Andy Sullivan is top of the Abu Dhabi HSBC Golf Championship leaderboard, after a fog-affected day two. The morning's misty conditions led to play getting under way around three hours late, and the knock-on effect also meant that a number of groups couldn't finish their rounds before sunset. Sullivan was part of a group that did complete the round, with the Englishman carding a second-straight 67, to go into the weekend on 10-under overall. He's a shot ahead of the amateur, Bryson DeChambeau, who is still to play the Back Nine in his second round. The group containing Rory McIlroy, Rickie Fowler (both tied for 9th on 5-under) and Jordan Spieth (T-26th, 3-under) and are also yet to finish their round, with bad-light stopping them at the end of the 13th hole. Three-time winner, Martin Kaymer, is on two-under through 12, for a 5-under overall, whilst in the same group Henrik Stenson is a shot further back, and Gary Stal, last year's champion, has work to do to make the cut, on one-over.
