According to Texas Leaguers, Chris Davis has seen 157 change-ups in 2012 so far. That is 9.6% of the pitches he has seen. An even shocking note (Or maybe not really considering it is Chris Davis) is that 75.8% of the Change-ups have been called strikes. 67.5% have been swung at and 20.4% have been whiffed on. These numbers are the highest for all the pitches thrown at him at least 100 times (4S, 2S, Slider, Curve, Sinker). That seems ridiculously high to me, even for Chris Davis. Looking at the chart from the entire year, it's pretty clear that the change (purple) has been primarily thrown low and away to Chris. http://pitchfx.texasleaguers.com/batter ... F16%2F2012
I am a little surprised he does not see more change ups to be honest after looking at this.
Chris has a long extension with his hands and can crush the ball opposite field when he makes contact. The hardest part for him is staying back on the ball. Especially the change.
