Within the last week, the Orioles have traded away two pitchers who were once mainstays in a vaunted bullpen. First, Zach Britton was dealt to the Yankees in exchange for three prospects on Tuesday. He was followed out the door by Brad Brach, who was sent to the Braves in a swap for international signing bonus money on Sunday. In both cases, the return was underwhelming considering how good the pair of pitchers had been when at their best in Baltimore. But given that both were approaching free agency, it wasn’t completely unexpected.
