Mike Sirotka. He had some good years with the White Sox, then was traded to Toronto. He immediately came up with shoulder problems, and Toronto asked for compensation or to void the trade (I don't remember which), claiming that he was damaged goods at the time of the trade. I think they lost that grievance. He signed a minor league deal with the Cubs, and I believe may have pitched some at Iowa, but he never pitched for the Cubs at the major league level. Unlike Miller, I think he was signed to a minor league contract.
