The distinctive noise when the titanium face of the club makes contact with the ball is like that of a rifle shot and Woods has regained the ability to shape the flight of his ball off the tee.
He said: "The shot I hit on 18 summed it up. I aimed down the right side of the fairway and just busted a high draw. When it works, like it did there, it makes you feel pretty good.
"To be able to shape shots like that is what I've been looking for."
The challenge facing Woods today is to catch Garcia. He and Herron were the only two players of 72 starters to return bogey-free rounds on a course made specially testing by ballburying rough and greens as hard as concrete.
