Woods' problems lie in his nerves and lack of confidence, says Harmon

Tiger Woods will be back in action at the Wells Fargo Championship this week for the first time since his disappointing 40th-place finish at the Masters.

He blamed poor ball-striking for his worst-ever performance at Augusta National as a professional, but his former swing coach Butch Harmon thinks the problems go deeper.

"I think he's lost his nerve putting," Harmon said in an interview with The Wall Street Journal. "I think his nerves are bad and he's lost his confidence."

Woods might care to remind the man who helped him hold all four major titles at the same time 11 years ago that he birdied the last two holes to win the Chevron World Challenge -- a limited-field, unofficial event admittedly -- in December and won the Arnold Palmer Invitational by five before heading to the Masters.

But Harmon also said: "I think everyone thought because he won at Bay Hill that he was back -- well, he didn't hit it great at Bay Hill, he hit it okay. And Bay Hill's not a major.

"For me, and I think we saw this at the Masters, he looks like he's playing golf-swing and not golf," he added. "In my opinion, he's very robotic and you could see that at Augusta with all his practice swings and the double-cross shots when he's trying to fade it and he hooks it.

"There comes a point where swing changes, no matter how sound and well-intended, can become counter-productive. There's so much more that goes into it than just the actual swing," he said. "He's changed so many times he may have confused himself."
