DD attended a clinic recently where the instructor was teaching lateral blocking technique. Specifically, he wanted the catchers to take a jab step to the side with their lead foot before going into their blocking slide. The idea was the jab step allowed the catcher to block balls that were farther outside than if she just slid over. The jab step is supposed to be quick and seamless. Up to this point DD has followed Weaver's technique, which as far as I've seen, there really is no intentional jab step involved. DD didn't feel comfortable doing a jab, but I'm sure if she practiced it enough she'd get it down.
I can see the point if a pitch is far off the plate and the catcher needs to cover more ground but not totally convinced it's worth the time and effort for 12U DD to change her technique. Anybody's catcher beast use a jab step when blocking to the side? Or have you seen it used in fastpitch?
