My son's tryout was in the Noirtheast and was run by the Yankees. They had 5 tryouts held over about 10 days in June of 2009. The cities were Pittsburgh, PA, Allentown, PA, Trenton, NJ, Richmound, Va, and the Boston area (Bentley College). We went at Allentown in a minor league stadium, with a scouts recommendation. There where over 60 college scouts plus another 20 MLB. My son did not make the team, but was definately recruited by many schools ( including where he signed ) out of this tryout. This was the single best thing he did during the recruiting process.
