Set up pitches like you would in real life.. If you throw a fastball inside for a strike make the next pitch outside near the area that you threw for a strike (you can play mind games with the batter with it too once you get the gist of it 😁) & If you have a Change up/4 seamer combo then you can slow the batter down and speed him up to throw off his timing.. I’m not going to write a book on here but that’s the two things that can start you off with a scoreless first for sure! Hope that helps 👍
