New to pitching and have a question about a pitchers pre-pitch stance.
I notice that when a pitcher (clemens for example) has no runners on he stands on the rubber facing forward and does a rocker step as he begins to pitch.
Although when there are runners on - he stands sideways with his right foot on the rubber.
Why the two diffent pre-pitch stances?
Some pitchers never use the rocker step and some do - regardless of runners on. Is this just a matter of personal preference?
