Try that with a runner on first. I remember Betts stealing second against the shift, and he never broke stride as he headed for third. There was no one covering. He was perfectly correct, of course. If he reached second, they were giving him third, there was no need to slide if he beat the throw. I think the infielder covering second was slightly stunned because he had never seen a base runner stealing second standing up and in in full stride.
Love it, have seen guys on first taking third by deking outfielders on a single, slowing down like they were going to stop at second and then taking off for third full speed after the outfielder had committed to a lazy throw back to the first base side.
