He holds MLB records for career stolen bases, runs, unintentional walks and leadoff home runs. At the time of his last major league game in 2003, the ten-time American League (AL) All-Star ranked among the sport's top 100 all-time home run hitters and was its all-time leader in walks. In 2009, he was inducted to the Baseball Hall of Fame on his first ballot appearance.
