NOTICE:

KOA

In agreement with DABA(Dormont) and CSYA(Castle Shannon) and in line with past practice, please note there may be situations, depending on registration numbers , where our 10U and 12U baseball teams will collectively play under the KOA banner.

In these situations, almost always the result of low registration numbers, teams may be formed jointly between boroughs and play as KOA teams. Team selection will be handled by the commissioners from all 3 boroughs.
 
In these instances players from Green Tree may be assigned to teams playing out of Dormont or Castle Shannon and vice versa, we may have some of their players come to us. Over the years we have used this model to help ensure that youth baseball players across the Keystone Oaks School District have a team to play on. The goal always being to keep the kids playing.
 
Please know, it is GTAA’s first priority to keep all of our players here in Green Tree and every effort will be made to have players play in the community in which they live.
