New York Yankees old timer Reggie Jackson waves to the crowd as he is introduced during the team's 59th annual Old Timer's Day ceremonies before their game against the Cleveland Indians at Yankee Stadium in New York in this July 9, 2005 file photo. Separated by a distance of sixty feet, six inches, Hall of Fame pitcher Bob Gibson and Hall of Fame hitter Jackson were once natural enemies. In retirement, however, the two share a mutual respect, a love of the game and 38 seasons of insight in "Sixty Feet, Six Inches," a collaborative book about baseball at the highest level.
