Certain organizations “share“ some of their PO, especially for the larger national stage events. For example your 18u team which is mostly 2020 grads has a couple of PO eligible to play at the 17u WWBA. So for that weekend they are with the 17s. When I’ve seen it done, those guys are already committed. I think it’s good to have the flexibility within your organization and large national events. 17s get the opportunity to show they can hit really good pitching. I don’t think college coaches mind.
