BLOOMFIELD HILLS TOWNSHIP, Mich. -- Andres Romero bogeyed the18th hole Friday morning to fall out of the first-round lead of the PGA Championship.

After a weather delay Thursday forced 18 players to return to the South Course at Oakland Hills, Romero dropped a shot at his final hole to fall out of a three-way tie when play was called Thursday night.

That left Robert Karlsson, who has a top-10 in all three majors in 2008, and India's Jeev Milkha Singh atop the leaderboard at two-under-par 68.

Romero fell into a tie for third with Sergio Garcia, Ken Duke, Billy Mayfair and Sean O'Hair at minus-one.

Phil Mickelson, the world No. 2 and 2005 PGA winner, shot an even-par 70 on Thursday. He is tied for eighth with two-time winner this year Anthony Kim, Brian Gay, 2007 U.S. Open champion Angel Cabrera, Ryan Moore, Rod Pampling, Charlie Wi and Michael Allen.
