The top two seeds have lived up their advance billing in the York-Adams American Legion baseball playoffs.
Second-seeded Dover or top-seeded Pleasureville will represent the local league in the upcoming Region 4 playoffs, which start in Hanover next weekend.
Hanover, by virtue of being the host site, was already assured of a berth in the regional tournament.
Dover (14-2) has gone 3-0 in the double-elimination York-Adams playoffs. Pleasureville (13-2-1), meanwhile, has gone 3-1, with its only loss coming to Dover on Friday, 15-4.
The two teams will meet at 1 p.m. Sunday at Shyrock Field, with Dover as the home team. If Dover wins that game, it will win the league playoff title and the regional berth.
If Pleasureville wins the 1 p.m. game, a second, winner-take-all game will follow at approximately 3:30 p.m., with the victor taking the league playoff crown and the regional bid.
