Just because a pitch is his second used pitch does not mean the call is two fingers. 3 is commonly a slider (with 2 being a curveball). 4 fingers (wiggled) is often a change up. Those are the common calls and not changed for the pitcher unless he has something like a split finger, screwball, knuckleball, etc.
It can change up depending on the pitcher, but just because the call is 3 fingers does not mean it's his 3rd pitch.
