Stolen base percentage

From BR Bullpen

A player's stolen base percentage (aka SB%) measures his rate of success in stealing bases. Because stolen bases tend to help a team less than times caught stealing hurt, a player needs to have a high stolen base percentage in order to contribute much value to his team. A commonly used figure is that a player needs to succeed about 2/3 of the time just to break even.

SB% = 100 * Stolen Bases/(Stolen Bases + Caught Stealing)
