Seems like the readings are completely off this year. The GABP gun has Cueto and Volquez topping out at 91-92, and sitting around 86-89 on their fastballs.
I can see without radar that they are throwing pretty hard, and other stadiums guns have them topping out at 94-96. MLB Gameday (Who I assume use their own gun) also show the pitches coming in 3-4 mph faster than the readings on tv.
Just seems strange as the GABP gun always seemed to add a mph or two in the past.
