Rory McIlroy and Tyrrell Hatton shared the 36-hole lead at the DP World Tour Championship in Dubai on Friday, with McIlroy at 5 under after birdieing the 18th. McIlroy, the world No. 2, is chasing a record-equalling eighth Race to Dubai title. ESPN reported that he made three bogeys in a six-hole stretch from the 12th at Jumeirah Golf Estates, where a stiff breeze, thick rough and dry, slippery greens made scoring hard. McIlroy, playing the course for the 17th time, said: "I feel like I salvaged the day a bit with that birdie." Hatton shot 69 and McIlroy 70 in the second round. Eugenio Chacarra, who leads McIlroy in the Race to Dubai standings by nearly 534 points, was four shots back after a 71 that included a chip-in at the last. Jon Rahm, three strokes off the lead, needs to win and needs McIlroy and Chacarra to finish well down the leaderboard. Patrick Reed, third in the standings, was 8 over after a second-round 77 and appears out of the running. The winner receives 2,000 points.
