I wonder if the newer strike zone has pushed the knucklers out a little? I mean, the old zone from what I remember, think back to Greg Maddux, was a little wider but it didn't go as high, anything just above the waist seemed to be called a ball back then, but you could get a good inch or two off the plate sometimes, especially if you had a good catcher. Now the strike zone seems to be narrowed but it seems to go more up and down, I see things called just below the knee and it goes pretty high up like maybe belly button high maybe depending on the ump up to the chest, think Odorizzi's high strikes. Since the knuckle ball seemed to move all over the place, those knucklball pitchers may have had an easier time throwing strikes if they could get an extra inch or two on the plate?? I have no idea why, but I'm just putting forth a guess here. It would seem that if you could get one who could throw strikes that it would be a good day for the bullpen to get a day off 20 times a year as those guys could throw forever it seemed.
