A ball?
Seriously - you need to tell us what you mean by "Batter presents at the pitch." Did batter move the bat toward the ball and just miss (badly!)? If so, strike. If the batter just stood there, then this is just a ball.
Is there something else to this question? (I only asked because you gave us runners, a count, and number of outs ... so maybe you thought there was something else going here other than the decision to rule on ball vs strike. If you did, I'm missing it.)
