Tiger Woods (book) 70,000 words in length. More than 250 people were interviewed for the book. Keteyian interviewed Mark O'Meara for the book while O'Meara was playing a round at the 2017 Conquistadores Classic. O'Meara's ex-wife, Alicia O'Meara, was also interviewed several times for the book. The authors declined an on-the-record interview Woods himself for the book as they were not willing to meet Woods' conditions for such an interview, and the authors were not able to conduct any off-the-record conversations with Woods himself. Keteyian said the reason for writing the book was to attempt to answer the question, "Who is Tiger Woods?"
Tiger Woods trails only Jack Nicklaus who leads with 18, and 80 PGA Tour events, second all-time behind Sam Snead (82). Woods leads all active golfers in career major wins and career PGA Tour wins. He is the youngest player to achieve the career Grand Slam, and the youngest and fastest to win 50 tournaments on tour. Additionally, Woods is only the second golfer (after Nicklaus) to have achieved a career Grand Slam three times. Woods has won 18 World Golf Championships, and won at least one of those events in each of the first 11 years after they began in 1999.
