Thanks, Doug. That tells me a little bit with regard to the movement. He may have moved up a little to get a little extra bite on the cutter, but I bet it has cost him some movement on his fastball.
The cool thing about Mariano Rivera's cutter and fastball is that they both come out of the same arm slot and release point which makes it extremely difficult to pick up. Lots of deception with the same release point, and he is basically a two pitch pitcher.
I have tried to ensure that all of my son's pitches (fastball, change, curve and cutter) come out of the same release point. He also throws close to over the top which gives him a great downward plane, and is a little different than most left-handers. He also has not sacrificed movement on his fastball by coming over the top which is also a little unusual. He is very difficult to square on a consistent basis. I have found that the release point being the same on all his pitches makes a huge difference.
