Maybe times have changed. Many years ago my daughter took some lessons from Danielle Henderson, former Olympian, All American, pitched in the NPF, now the head coach at UMass. She taught HE.
How about make a called strike = 2 strikes. A lot of young players learn very quick they can just stand there and statistically get on base. One good called strike and now the pressure is on the batter, anything close you got to swing.I had another idea today I thought I'd throw out. Instead of limiting an at bat to 4 balls (and maybe 2 strikes), why not expand the number of pitches before a batter could take a base? For example, expand it to 12. If you reach the limit then there's a walk. But if you don't reach the limit that means there was either a K or a W after 12 pitches.
This would take some of the immediate pressure off pitchers who are working on becoming real pitchers. Hopefully in 12 pitches they could find the plate 3 times. That's 25% accuracy, which should be achievable.
