Rickey Henderson, the thrilling and charismatic Hall of Fame outfielder who, with his signature crouched stance, blazing speed and unlikely home run power, was widely regarded as the greatest leadoff hitter in Major League Baseball history, died Friday. He was 65. His death was announced by his family. They did not cite a cause or say where he died, but they thanked the staff at the University of California, San Francisco Medical Center. Often called “the man of steal” by sports writers, Henderson holds the career record for stolen bases with 1,406.
