Although the PG events are a great venue and the most respected and well known showcase events out there, they are not always right for all players. As fenwaysouth points out, you need to define what schools you are interested in, and a lot of that has to do with your ability both as a baseball player and academically.
Both fenwaysouth and I have recently had son's go the more academic route. Personally, my son never attended a PG showcase event, yet had strong interest and committed to a fine academic D1 school by the end of July in his Junior year summer.
If I can help you in any way going forward please let me know.
