Its a hurry up and wait day. Good experience for the players. But you be in the top 1% or forget it. When my son went it seem pretty obvious that the people running the show had most of the team already picked. They were very friendly to them and cold shoulder to the rest. Some of the parents already knew who was going an who wasn't.
There was on kid warming up in the ball pen who told the pitchers his elbow was sore, but this was big showcase and going to let it all out. When he got called to the mound he threw two or three pitches on the next his elbow snapped, sounds little it got hit with a bat, ball when over the back stop, compound brake, they carried him off the field screaming and continued like nothing happened. It was crazy.
