Notes [ ]
^ Prior to 1898, a player was credited with a stolen base if he took an extra base on a base hit by another player. For example, a baserunner is on first base and the batter singles to right field. If the baserunner reaches second base, then proceeds to take third, he would be credited with a stolen base. The single-season record under modern rules is 130 by Rickey Henderson in 1982 .
