The former world number one has won the Green Jacket on four occasions, but not since 2005.

And while he was considered to have been at his best during the 'Tiger Slam' of 2000/01, he says that the game has moved on since then.

"Consistently, with this type of control, it has been a few years," Woods said. "As far as having the speed and the pop in my game, it has been a very long time.

"I think I have more shots than I did in 2000. I guess I'm not driving the ball as far, but I'm longer than I was in 2000. So it's a different game. The guys are much taller, much bigger, much more athletic.

"The game has become bigger and stronger. Before, when I played back in 2000, the big carry was 280 (yards). That was a big carry over a corner. Now that has been moved out to 315, 320. It's just a different number now."

"As far as controlling my game, I feel like I'm hitting the ball just as consistently day in and day out as I did then."

With a victory on Sunday, Woods could also match Jack Nicklaus for second on the all-time US PGA win list with a 73rd overall crown, nine shy of Sam Snead's all-time record.

"I would like the green jacket more," Woods said. "I know the 73 would be a by-product of it, but I'm here for the green jacket."
