Assuming you have a coach that is capable of simulating high school pitching... Split the 12 players into 3 groups of 4. One group is up to bat. This always gives you someone to bat even if the bases are loaded. Have the other two groups in the field. Along with the coach/pitcher, that gives you 9 players to cover the positions. Play to 3 outs, empty the bases, and play to 3 outs a second time. Once the second simulated inning ends, move the hitting group to the field and replace with one of the other two groups. Rinse and repeat... Each of the coaches can help instruct the fielders and runners regarding situations. Where do I throw the ball? Who is responsible for backing up? When can i take an extra base? Etc., etc. I have used a similar process with my travel teams for years and it seems to help prepare them for game situations. Much better then them standing there and me hitting ground balls to them. Good luck in playoffs!
