4thGen attended a TPX event last fall and we were very pleased with it. They are really instruction camps, rather then showcases. While you run through the showcase type activities the morning of the first day, most of the rest of the time is taken up with teaching stations where you are graded as well. The kids each get a written and verbal evaluations from one of the college coaches and you can get a video analysis of each component of your game. The games at the end were mainly to analyze pitchers. The events don’t attract a lot of high profile coaches to watch, but you can take the evaluation and video and make it available to coaches after the event. Getting the feedback and evaluations is invaluable.
