Book excerpt: Bob Harig's Tiger & Phil provides an in-depth chronicle of the decades-long rivalry that drove the success of golf's two biggest stars, Tiger Woods and Phil Mickelson. For more than two decades, there have been two golfers who have captivated, bemused, inspired, frustrated, fascinated, and entertained us, and in doing so have demanded our attention – Tiger Woods and Phil Mickelson. Even with all the ink that has been spilled on Tiger, no one has ever written about his relationship with Phil and how their careers have been inextricably intertwined. Furthermore, very little has been written about Phil Mickelson, who is more than just an adversary. He is a fascinating Hall of Fame golfer in his own right. These two biggest names (and draws) in golf have, for better and for worse, been the ultimate rivals. But it is so much more complicated than that. Each player has pushed the other to be better. They have teased each other and fought. They have battled to the bitter end on the course making for some of the greatest moments in the game for the last 20 years. They have each gone through injury and health problems, legal problems, falling in and out of favor with the press. And over the course of their time together in the game they have gradually become not just rivals but friends. In the tradition of major bestsellers such as Arnie & Jack, When the Game Was Ours, The Rivals, and Brady vs. Manning, Tiger & Phil will change the way we look at these players and the game itself.
