All right, let’s take it one thing at a time.
When Jim Brosnan was pitching for the St. Louis Cardinals he was having trouble with both his two-seam and his four-seam fast ball, and he complained to pitching coach Clyde King about it. King called in a catcher, and he had Brosnan throw for about ten minutes. Then he told him to stick with the two-seamer, because it was working better for him, he had better control of that pitch. So at least for the time being you might do the same thing—stay with the two-seamer, and maybe try to develop a sink on that pitch.
As far as control goes—I remember when I was a little snip of 12 or 13, I would get hold of a catcher and we’d play a game we called “ball and strike”. The whole idea was to work on location, on hitting various spots, and I had the catcher position his glove in one spot or another and move to various corners, and I would practice throwing to those spots—a terrific way to sharpen up control.
And you might want to think about working up a new pitch, as you indicated. I didn’t have anything resembling a fast ball, so I had to go to the “snake jazz”—breaking pitches of various kinds. You might experiment there—try working up a knuckle-curve, a palm ball or some other pitch that is easy to throw and control and very, very hard to hit…And ever think of something like a splitter? There are possibilities galore—you should consider a couple of them. Let me know how you make out with this. I’m interested.
