Woods is currently four-over going into the final round, just a week after winning the Bridgestone Invitational by seven shots.
He also insisted that he is not trying too hard to win another Major, having failed to add to his 14 victories since 2008.
"[It was] not joyous, that's for sure," said Woods when asked to sum up his performance.
"It's just one of those weeks where I didn't quite hit it well enough and didn't make enough putts. That's golf. We don't play well every week.
"As far as [trying too hard] is concerned, no. I've been in there in enough of these things where I've been right there in the back nine on Sunday with a chance."
