On December 9, 2009, Coke was traded to the Detroit Tigers as part of a three team trade that sent Curtis Granderson to the Yankees.
The Tigers signed Coke to a new contract on February 7, 2011. After
spending all of his previous time in the major leagues as a relief
pitcher, Coke was moved from the bullpen to the fifth spot in the
starting rotation to start the 2011 season. On June 30, after accumulating a 1–8 record, Coke was moved back to the bullpen.
