Deletion of Orioles-Pirates rivalry

Comment: Not only do all these articles fail  by a wide margin, there's nothing in any of these articles asserts the notability of these rivalries in any way -- indeed, they do not even assert the '''presence''' of a rivalry between the two teams. Heck, given the content of the articles, they could all simply be retitled "List of cool things that happened in games between (x) and the Pirates", which, while it might be interesting, makes them nothing more than |lists of trivia
