Rickey Nelson Henley Henderson is an American former professional baseball left fielder who played 25 seasons in Major League Baseball (MLB) for nine teams from 1979 to 2003, including four separate tenures with his original team, the Oakland Athletics. Nicknamed "the Man of Steal", he is widely regarded as baseball's greatest leadoff hitter and baserunner. 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.

In baseball, a home run is scored when the ball is hit in such a way that the batter is able to circle the bases and reach home plate safely in one play without any errors being committed by the defensive team. A home run is usually achieved by hitting the ball over the outfield fence between the foul poles without the ball touching the field.
