It is not normally an option. When they say they want to see you play, they are actually saying this is where you need to play. It is like optional practice, not really optional. They will usually put them on an inning count according to how much they pitch during regular season. Schools have connections with certain teams in certain leagues. My son got the option of Coastal Plains or California. He chose Coastal Plains because it is where we live. He wanted to be able to be a little this summer and get to see friends and friends/family come watch him play. There was a team real near us but that is not who his school is affiliated with so he is playing a little further away. His contract has all details in it so he will know what he is obligated to pay, if any and any other details. It is a binding contract which usually prohibits him from playing anywhere else during the summer. It is a long summer and sometimes very boring for pitchers because they play every day and only pitch once a week or so. They can be involved in activities and keep stats and some announce games. They say you can work a part-time job and many will help you get one but that depends on travel. The Coastal Plains league travels almost every other day and many of those are 6-8 hours away. Makes short nights on the way home and they play the next night.
