Guys, just a heads up, Houston is using the pitch tracking system, which is linked to the MLB gameday system. Anytime I see a pitch called a way I don't agree with, I run in to see how gameday placed it. 2nd guess the umpires and Don Sutton too. This system gives precise speed, break and location data. Note the location is per the front of the plate.
