Jason Day was 1-under-par through the front nine Friday, but his round took a turn for the worse on the back nine with 41. The 29-year-old Australian was able to make the cut on the number at 6-over.
Day started with birdies on Nos. 2 and 3, where he dialed in a wedge to two feet. But he bogeyed No. 10 and took a double at No. 11. He rallied with a birdie at No. 13, but followed with bogeys on his next two holes.
Day is fourth in driving distance this week at 288 yards, but his ball striking has been off as he ranks 60th in greens in regulation at 52.78 percent.
Day said the weather would be perfect for going low on the weekend, which he is going to have to do to climb back into contention.
