Yea, he looks like a guy who could change his approach a touch. That's fair. He obviously is swinging and missing at a lot of pitches.
The other thing in this situation to consider though - knowing that he needs to cut down on Ks, he may stop going deeper into counts and put the ball in play quicker. There are a decent amount of guys who strike out AND get on base by walking quite a bit, these are guys who are working counts and waiting for "their pitch." The 2-1 pitch on the black may be something Curtis would swing at now, not making great contact, where before, maybe he would have taken it.
It's probably not the best example. I did mention what seems like forever ago in this thread that guys seem to not be situational hitting as well as they used to, and used Granderson as an example.
