Rickey Nelson Henley Henderson (December 25, 1958 – December 20, 2024), nicknamed "Man of Steal", was an American 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. 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 10-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 in his first year of eligibility.
Henderson holds the single-season record for stolen bases (130 in 1982) and is the only player in AL history to steal 100 bases in a season, having done so three times (in 1980, 1982, and 1983). His 1,406 career steals is nearly 50% higher than the previous record of 938 by Lou Brock. Henderson is the all-time stolen base leader for the Oakland Athletics and previously held the New York Yankees' franchise record from 1988 to 2011.
