Trevor Rosenthal was supposed to be the centerpiece of the Oakland A’s completely revamped bullpen. He was their biggest free agent signing, costing the team $11 million, although a large portion was deferred. Rosenthal was meant to take over in the ninth inning, continuing the A’s history of dominant closers.
But you know what they say about the best laid plans of men. Rosenthal was placed on the Injured List just before Opening Day, and later underwent surgery for thoracic outlet syndrome.
