Change in Slider Value: 2016 Edition

Using total bases per 100 pitches as a measure of effectiveness, I compared 2015 to 2016. I also compared balls per 100 pitches, but with a few exceptions those were fairly stable over the two seasons. A lower TB/100 and B/100 is better, so a negative number signifies an improvement and a positive number shows the pitch was worse in 2016 than in 2015.
