Hi wc8,
I've seen low volicity pitchers very effective, espically coming in after someone throwing upper 80's low 90's.
I agree with CADad, good grades will make a difference. You sould talk to your HS coach about schools he could recommend. You sould also consider looking at the web sites of some D2, D3, NAIA and JUCO's you would want to attend even if you did not play baseball. See if you can find out about their current pitching staff and their volicities.
Go visit the schools you find interesting and try to talk to the coaches. Fall is a great time to do this because their schedules are not as hectic. Ask the coaches what events they attend for recruiting and try to go to those. Let the coach know you are going to be at an event.
Best thing I can advise is to be a little agressive in contacting the schools and coaches, don't simply go to these "showcase" events then sit back and wait for them to come to you!
