The injuries are relevant because Woods has had four surgeries on his left knee, and he withdrew from his last tournament two weeks ago at Doral with tightness in his left Achilles tendon. That's the same one that caused him to miss two majors last year.

Woods said it was only a mild strain, and he is scheduled to play seven straight days this week, including at Bay Hill.

While the injuries are timely, the rest of the book is sure to satisfy the curiosity of taylorMade RocketBallz Fairway Woods

 fans - particularly those who have watched him win at a record rate - to whom Woods has revealed so little over the years.

Haney became increasingly concerned when Woods began workouts designed to build muscle. It reached a point when Haney and former trainer Keith Kleven tried to persuade Woods that he was getting more muscular in the upper body than was helpful for golf.

Woods so badly wanted to be considered a real athlete that he saw injuries as a badge of honor. Haney said Woods tried to empathize with Derek Jeter and Shaquille O'Neal when talking about injuries.

Haney does not consider the book a "tell-all," and much of it reveals Woods' pursuit of his place in history. He also delves into the relationship Woods had with his ex-wife, and how guarded they were in public.

That runs against his comments in January that the book would be about ping golf clubs , though Haney felt it was relevant.

"I think when you're such a complex person, an absolute superstar, you can't ignore everything that happens off the golf course," Haney said in an interview. "The performance, the dedication, the ability to compete with a clear mind. To me, it said something about Tiger overall as a person. Clearly, there's a lot of things I left out of the book that didn't have to do with cheap taylorMade RocketBallz Fairway Woods

He said Woods ignored phone calls when they started working together, but later began returning text messages. Haney said he was not aware of Woods' extramarital affairs, except for Woods making the occasional comment about a woman he saw in the gallery. He also wrote that Woods told him his ex-wife wanted him to take two years away from golf after his serial adultery was exposed.

"One of my goals in the book was to paint a picture and let people decide what they want to glean from it," he said.

Haney said he felt as though he had won the lottery when Woods called him in 2004 and asked him to be his swing coach. He was paid $50,000 a year, plus a $25,000 bonus for Woods winning a major.

He said they had to confront three issues in revamping the swing - protecting the left knee (Woods told him his anterior cruciate ligament was only 20 percent intact after surgery in 2002), the movement of his head and learning to hit the driver.

"Simply put, Tiger played the TaylorMade RocketBallz Fairway Woods

 with a lot of fear," Haney wrote.

He said their second lesson was his first test as a coach. Woods had finished 10 shots behind at Bay Hill, and Haney met him on the range at Isleworth. He said Woods ignored him.

"The message Tiger wanted to send was clear: "When I play bad, when I don't win, it's your fault." He was reminding me that his expectations were going to be incredibly high ..." Haney wrote.

".... I also realized that I was never going to be able to relax with Tiger Woods," he wrote. "He was going to be complicated, and he was going to surprise me with his moods."

Haney expects to be criticized for trying to make money off his six years coaching Woods, especially with the book going on sale a week before the Masters. He has said on Twitter in recent months that the memories do not solely belong to Woods.

"I wanted to write the book about my observations of greatness, an athlete superior to his competition," Haney said. "Obviously, people will have their thoughts. But when people read the book in its entirety ... if Tiger read the book, in his heart, he'd have to say it's an accurate portrayal, and it's honest."

Perhaps a more accurate assessment is something Haney wrote late in the 247-page book.
