The guns are most certainly juiced.

Any pitcher dad will understand the difficulty it is to pick up 1 to 2 mph. It's exponentially more difficult the faster the pitch.

I heard one pitcher asked about it and her response was she can throw that fast (68-70) but her ball flattens out and the it's hammer time. Basically stating she wasn't pitching what the speed indicated.

Yet, I'm to believe that a certain TN pitcher went from throwing 70 to 78+ mph? Don't get me wrong, she is a phenom, but not a 78+mph phenom.

High pitch speeds generate publicity for the sport.
