LHP comes set, on the rubber, with a runner on 1b. Steps with his pivot foot (left foot) toward first but does not throw the ball.
I know it would be if he had stepped with his right foot, much like a RHP does for a fake to 3b.
What has gotten me is whether stepping with the pivot foot, toward 1b, constitutes as disengaging from the rubber, thereby allowing the pitcher to fake the throw.
Thanks for any insight.
