Zumaya, 26, has managed just 109 appearances over the last four years. In 2010, he made 31 appearances, the most since his rookie year of 2006, before leaving a game in June with an elbow injury, ending his season. He's also struggled with shoulder injuries and a ruptured tendon in his finger.
"This year's going to be my make-it-or-break-it year," Zumaya said. "If I get hurt again, I'm basically going to be done with baseball. I'm going to have to find another job."
Zumaya is a year away from free agency, and is a candidate to be non-tendered at Thursday's deadline by the Tigers. However, he told MLB.com that the team has told him they won't non-tender him. Zumaya hopes to avoid arbitration and sign a one-year deal with Detroit.
Zumaya made $915,000 last year.
"I'm not going to be a guy that's going to take advantage of the Tigers," Zumaya said. "I do know what i can get for arbitration. I'm not greedy."
Zumaya has gotten the go-ahead to start throwing to prepare for 2011 and expects to begin throwing soon.
