Shoot, even if they don't ask for our previous summer's record, we give it to them. And we will do that again this fall, even though our summer 2010 win-loss record wasn't all that great. All that experience (including losses) against the top 10-20 teams in the state set us up for our finish as the second highest placing team from Ohio at the 14U USA/ASA Nationals. Plus most of our summer losses were by 1-2 runs.
An effective application to an invitational requires a LOT of time and thought. Just filling out the form won't get it unless you are a team who has the reputation of a Doom or Lasers team.
