We expected some changes for May Day, and the Detroit Tigers delivered. Veteran right-hander Kenta Maeda, whose two-year, $24 million contract has not worked out, was designated for assignment on Thursday. Right-handed relief prospect Tyler Owens has been promoted from Triple-A Toledo and will make his major league debut in their road series against the Angels in Anaheim. In a related move, left-hander Andrew Chafin has exercised his opt-out from the minor league deal he signed with the Tigers, and has signed a major league contract worth a guaranteed one million dollars with the Washington Nationals.
