I will say that..unless she is conditioned beyond belief her speed will drop off, I wont name names but the kid that throws a 64 mph rise in the first inning is a flat 60 by the 5th,,,,,,, depending on how many pitches shes thrown, the heat, a females curse once a month,staying up to late texting the night before.and so on, if a pitcher lived in a vaccum and had no outside indluences maybe her speed would remain consistant....dosent happen in the real world, at least not the world we have played in the last 6 years
