Ahead of last Monday’s non-waiver trade deadline, the Orioles made their fifth and sixth deadline deals in the past four years. And on Thursday, the ramifications of one of those deals began to play out, as Wade Miley made his Orioles debut at Camden Yards and Ariel Miranda made his Mariners debut in Seattle.
