Tiger Woods admits he needs to shoot "something in the mid-60s" if he is to get himself back into contention at the US Masters.
The 14-time major winner has shown plenty of encouraging signs in recent months and appears to be regaining some of his previous form following three separate rounds of back surgery.
However, he has struggled to build any momentum at Augusta, adding a 75 on Friday to his opening 73 to leave himself on four-over, just two-shots inside the cut and 13 behind leader Patrick Reed.
I need to get myself back up there.Tiger Woods
After opening his second round with a bogey, the 42-year-old failed to get going, carding a double at the sixth before making two birdies on the back nine, only to see them cancelled out by a pair of bogeys.
It means he has his work cut out if he is to win a fifth Green Jacket and Tiger admits he will need luck to go his way over the weekend.
With the weather expected to change to heavy rain and plenty of wind, Woods says he is looking to use his experience to go low.
"I need a lot of help but also I need to go out there and do my job," he told Sky Sports. "I need to shoot something in the mid-60s both days, but I'm so far back I'm not really in control of my own destiny here.
"I need to get myself back up there somehow with a low one tomorrow and we'll see what the weather holds out."
Woods is 11/10 to shoot 71 or under on Saturday and 4/6 to win his third-round three-back with Ian Poulter.
