fillsfan,
Sorry, I missed this earlier. The biggest difference between the two is that the World is much more selective. However, the open is much more likely to produce big surprises. They are played together so scouts have an opportunity to see everyone. The World is heavily scouted and typically as many as a dozen of the 30 MLB scouting directors attend. It has had many current Major league players attend in past years. These events are not for everyone, but the results have been very good over the years.
New2This,
Before they changed the recruiting schedule many of the top colleges attended the World Showcase. Now, whether it is a quiet period or dead period... These college coaches didn't die. Many players have become high recruiting priorities based on what happened at the World Showcase. Also, many of those players in attendance have already signed with a college, they are there for different reasons.
A couple weeks ago we had an uncommited player show up in an event in Arizona. He is from Oregon, we were not aware of him before hand! We recived at least a dozen inquiries from DI schools (East and West) who were not there about him within the next week. He is going to be a DI player if that is what he wants. Maybe even a draft pick. Evidently he had one offer from a Juco before that event.
I don't think everyone should go to these winter events, but if someone is an outstanding player... the results have been very good. We do have some credibility with college coaches throughout the country. They will definitely be looking at what happens at these events. They will be talking to us, the MLB scouts and "others" who were there. Why wouldn't they? College coaches are aware of the amount of talent that attends this event. They actually focus on what happens there.
If anyone has any doubts or expects any miracles by simply showing up... I would not attend these events.
