Following his Tommy John surgery Trevor Rosenthal was released by the St. Louis Cardinals. He focused on his rehab, and used Twitter to hype up his return, and it worked. His high speeds were on display as he was on the road to recovery.
Eventually, Rosenthal did a showcase for several teams, and the Cardinals were in attendance. However, the team was not expected to pursue the right handed bullpen anchor. There was not much time to change their mind, as Bob Nightengale reported the news of Rosy’s new deal.
