Kaka on top of the world
The American world number one racked up seven victories on the 2007 PGA Tour, including his 13th major title at the PGA Championship in August.
He also enjoyed a golden campaign in 2000, winning the last three majors of the season along with eight other tournaments worldwide.
"I think this year was very close to doing that. I was just four shots away."
"I had a great chance to win three of the four majors this year. I finished second in two of them and was just a few shots away from basically doing what I did in 2000.
"If I get those done, people would probably be comparing it (this season) to 2000, if not better."
