tzemaitis: On the 3-1 move, the pitcher has fully satisfied the feint to third as long as he has stepped towards third and feinted a throw with his arm. As such, he does NOT need to disengage while reversing course and throwing to first base. However, it is important to realize that the pitcher is still engaged with the rubber so the pitcher must throw to first in this case or be subject to a balk since the pitcher is not allowed to feint to first base. If the pitcher does disengage while feinting to third, then the pitcher may feint to first because his status is now that of an infielder.
That is, if he acts as a non-field player, then he should continue to act as well, right?
