There was a lot of uncertainty: Tiger Woods

Tiger Woods celebrated his sixth title of the season at the BMW Championship on Sunday and described the year as one of his most successful despite failing to win a major.

"Absolutely, it's one of my best years," said Woods, after romping to an eight-stroke victory at Cog Hill Golf and Country Club. "There's no doubt about that.

"I haven't won as many times as I did in 2000, didn't win any majors this year.

"But I've never had a year where I've been this consistent, either, this many high finishes and the number of events I've played.

"To have an opportunity just about every time I tee it up to win the championship on the back nine, that's something that I can't tell you how proud I am."

Woods has traditionally judged his success by the major championships he is able to win but this year, after recovering from reconstructive knee surgery, the 33-year-old American is using a different measure.

"There were so many uncertainties at the beginning of the season," said Woods. "I didn't know how the leg was going to respond.

"I can't remember the last time I had a leg that was stable, that didn't hurt when I played.

"There were so many different things that I didn't know and I hadn't played competitively since the (U.S.) Open (in 2008).

"A lot of guys had played well and I hadn't played at all.

"So there was a lot of uncertainty.

"To come back and be ...this consistent feels pretty good."

Woods returned to the PGA Tour in March at the World Golf Championships-Accenture Match Play Championship finishing tied for 17th. In his following 15 starts he has finished out of the top 10 only twice.

In six events since failing to make the cut at the British Open in August, he has won three tournaments and finished second twice.

He has won nearly $10 million and heads to Atlanta for the season-ending Tour Championship, and a possible $10 million bonus, in two weeks leading the FedEx Cup standings.

"It (Tour Championship) is very important because it's the top 30 hottest players of the year playing the season-ending event. This is the hottest field you'll probably have all year.

"If you would have asked me at the beginning of the year, any of you guys probably wouldn't have predicted I would have had the year like I have.

"To have the opportunity to win just about every tournament I have been in...to come off knee surgery and have this type of year and be this consistent is something I'm very proud of."
