Doral, Florida:Overnight joint leader Jeev Milkha Singh could not recreate the opening round magic and turned in a one-under 71 to slip to the tied eighth spot after the halfway stage of the USD 8.5 million World Golf Championships here.
Jeev, who outshone mega stars like Tiger Woods with an opening round 65, faltered on a treacherous back nine and was five strokes off the pace after two days with a total of eight-under 136.
The Chandigarh-pro shares the eighth spot with, among others, England's Ryder Cup star Ian Poulter (67).
Off to a brilliant birdie-birdie start, Jeev completed a flaw-less front nine after picking up another stroke on the eighth to make the turn three-under.
The back-nine started equally well for the Indian as he reeled off birdies on the 10th and 12th but it all went downhill thereafter as he stumbled to back-to-back bogeys on the 13th and 14th.
Had it not been for a 16th-hole birdie, Jeev would have failed to break par as he had a disastrous bogey-double bogey end to his day at the Doral Golf Resort and Spa.
At the top, American Phil Mickelson grabbed a two-stroke lead after a second-round 66 that left his total at 13-under 133.
Nick Watney (67) held the sole second spot, followed by Kenny Perry (64), Rory McIlroy (66) a stroke behind.
