Tiger Woods squandered the chance to take a commanding lead in the Tour Championship in Atlanta with an untidy finish to second round, ending a sun-splashed day just one ahead of the chasing pack.
The world number one lipped out with four-foot putts at the 15th and 16th before bogeying the par-three last for a two-under-par 68 at East Lake Golf Club.
That left Woods at five-under 135 in the PGA Tour's lucrative FedExCup playoff event, a stroke in front of playing partner Padraig Harrington (69) and overnight leader Sean O'Hair (70) of the U.S.
South African Ernie Els, boosted by four birdies in five holes from the eighth, was alone in fourth place at three under after carding a 66.
