Tiger Woods has issued an ominous warning to his rivals by claiming that he is still improving.
And after winning a record sixth Buick Invitational, the world number one reiterated his belief that a Grand Slam of all four majors is within his grasp.
Woods, who won three of the four majors in 2000, said: "I'm hitting shots that I never could hit before, even in 2000. I'm actually hitting the ball better.
"Do I see it (the Grand Slam) as a possibility? I say 'yes'."
His eight-stroke victory at Torrey Pines sealed Woods's 62nd PGA Tour title, and his 16th in 32 starts since 2006.
The San Diego course will be the venue for this year's US Open, and the future looks bleak for the American's rivals.
