Cut fastball or nothing

Hey guys I’m having trouble getting any type of arm side movement (i’m rhp). My two seamer/sinker either goes completely straight or it cuts into a lefty with no trail or downward movement. I try and throw everyday and use pronation and tried different finger pressures but nothing. I’m getting quite frustrated. Can you help me?

What’s your arm slot?

I have a 3/4 to overhand

Have you thought about dropping down to a sidearm delivery? That might help; that delivery is the easiest on the arm and shoulder and could take a lot of pressure off. Also, you might try doing what pitcher Mark Buehrle does—work a lot faster. And make sure that when you follow through you’re in a good fielding position. Give all this a try and let me know what happens.
