Joel Zumaya impressed local media throwing in the bullpen, but abruptly ended his session, walking off the mound with trainer Rick McWane. Zumaya said he was OK but later GM Terry Ryan acknowledged that Zumaya had felt discomfort on the inside of his elbow. He will undergo an MRI on Sunday.
Zumaya has a lengthy injury history, including missing all of last year with an elbow injury that happened in his first spring training start.
The Twins signed Zumaya in January to a one year, non-guaranteed, Major League contract. It is worth $800,000 with incentives if he makes the Opening Day roster. If he does not make the Opening Day roster, the team will pay him $400,000.
