Tigers Woods failed to take advantage of perfect conditions and fell off the pace at the inaugural Turkish Airlines Open in Antalya.
Despite thunderstorms and torrential rain delaying the start by three hours, the soft greens and dying wind meant scoring conditions were perfect.
But world number one Woods only managed to get to one under par in his 10 holes before bad light forced him off the course.
Tied for 50th in a 78 man field, Woods lies six shots behind Englishmen Paul Casey and Steve Webster (both thru 14) along with South African Darren Fichardt (thru 12) and faces an uphill battle to get back in to contention.
Woods had made the perfect start after hitting a wedge shot to within four feet of the hole on the opening par five and polishing off a simple putt for a birdie.
More pars, including a good up and down save on the fourth, saw him going steadily. When he hit a good birdie two at the eighth it looked as though Woods would kick on but he failed to capitalise on the next hole and dropped a shot to remain at one under.
Joint leader Paul Casey had a great day on the course after firing four birdies off the first four holes and still has four to play to finish the first round.
"I really thought you've got to get off to a quick one and I did exactly that," said Casey to Sky Sports.
"It was foot flat to the floor today and just fire at the pins, take advantage of the soft conditions and see what happens."
