There is no way to reschedule a tournament like this. They need to work around the quiet/dead periods and other events they have scheduled.
They will have games there this weekend. Has your son checked in with the coaches coming to watch him to see what they are doing? Does your son hit and play other positions or were you just going for him to pitch one game?
I know it's a massive tournament but they need to have a back up plan. Irresponsible of an organization like PG to not have a back up plan for a 200+ team during hurricane season on the Florida coast. No sympathy for them on that!!
I can not see how in the world there will be games in the Ft. Myers area this weekend with all the rain they already have had and are about to get. But then again, I don't live in the area so I have no idea how well the area can absorb the water.
My son is a PO on his showcase team. He hits and plays infield for his HS. He has several camps he is attending over the rest of the fall, so he'll be seen by the schools he is really interested in, but he can't get to all the camps he'd like too.
