Runners attempting to steal will strive to get as far ahead as possible, putting them at danger of being picked off. Pickoffs are most common at first base; the pitcher will swiftly deliver the ball to the first baseman, who will try to tag the possible base-stealing runner with the baseball before pitching. Jackie Robinson accomplished this feat during the 1955 World Series. A double steal is a play in which two runners on different bases attempt to steal the base ahead of them at the same time. This can entail first and second basemen sprinting to second and third, but it can also be employed to hide a steal attempt.
