Jason Day and Jordan Spieth went in opposite directions Friday at the Australian Open.
Day had four consecutive birdies on the back nine, including a 30-footer, for a three-under-par 68 that left him a stroke out of the second-round lead. Australian Lucas Herbert, who shot 66, is in front with a nine-under total of 133 on The Australian course in Sydney.
First-round leader Cameron Davis, who shot 72 Friday, is another stroke behind in third.
Defending champion Spieth earlier failed to take advantage of ideal morning scoring conditions and had a 71 to fall further behind the leaders — eight strokes behind Herbert and tied for 19th place with 10 others.
