Wally....
My son went last year when he was a sophomore, and will be going again this year.
Last year they had 4 teams of 15 players each. They ran the 60 yard dash, pitchers did 'bullpens' and threw for 2 innings in the game they were scheduled to play in. Catchers did pop times, hitters got about 6-8 swings.
During games, the hitters usually had anywhere from 3 to 5 trips to the plate in any game they were in. They played 3, 7 inning games. This was a very well run camp, and everyone at ND was super.
This years format appears to be a little different as the application shows there will be only 2 games played. It's still a great school and campus to visit, and the event will be fun to attend.
