Jon Meoli, Orioles beat reporter: For the entire length of July, the prices for trades around baseball were eye-popping. Prospects are seemingly valued more than ever, but the prices for both rentals and long-term assets were still high. Acquiring Wade Miley and Steve Pearce for the relatively low prices of Ariel Miranda and Jonah Heim, respectively, is sound business for the Orioles, even if those aren’t impact acquisitions. Miley is an upgrade only in the sense that he’s a reliable fill-in for the Ubaldo Jimenez/Vance Worley spot in the rotation, while Pearce could be a good platoon bat in left field with Hyun Soo Kim and can fill in in a lot of places.
