DUBAI, United Arab Emirates (AP) - Top-ranked Rory McIlroy and No. 2 Luke Donald share the lead with Marc Warren after the second round of the Dubai World Championship.

Donald joined McIlroy and Warren at 11-under 133 after his approach shot came within a foot of the hole on the 18th and he made the birdie putt for a 4-under 68. Warren (67), a 189th-ranked golfer who hasn't had a win since 2007, had a chance take the outright lead. But his 12-foot putt on the 18th came up short.

McIlroy (67) looks to win the season-ending tournament after wrapping up the European and PGA tour money titles. McIlroy was a shot behind Donald after the first round but had six birdies with a lone bogey to move atop the leaderboard.
