Woods won the WGC Championship at The Grove by eight shots

After becoming the first player to win at least eight times on the PGA Tour in three different seasons (1999, 2000 and 2006), he says he is still improving.

"I can control the ball better, I am hitting the ball further and I want to improve," said the American, 30.

"Golf is a fluid and evolving game and you have always got to keep pushing yourself to get better."

Woods also said that his performances this year vindicated the swing changes he made after his brilliant 2000 season when he won three majors and nine times overall.

"I think it's interesting how I was getting ripped for making my swing changes, now here we are," he said.

"That's why I made those changes. It's nice to have the opportunity to do the things I know I can do in this game."

Woods even reiterated his belief that he can win all four majors in one year.

"You've got to have a lot of things go your way but it's still only four," he said.

Woods has eclipsed Sam Snead, Byron Nelson, Ben Hogan and Arnold Palmer, who all won eight events twice.

His WGC Championship win at The Grove also means he has extended his run of successive strokeplay wins to six, among them The Open and US PGA.

"Eight wins on the PGA Tour and one in Dubai, nine wins, that's a good year," said Woods. "Two majors in there, as well, and a couple of World Golf Championships.

"Overall, the things I've been working on the past couple of years are finally starting to come together. It's nice to see the fruits of all the hard labour."
