Tigers make pregame moves, option Kreidler and Hill while adding Holton and Lorenzen.

The Detroit Tigers have optioned Ryan Kreidler to Triple-A Toledo to improve his offense, while activating Michael Lorenzen from the injured list and calling up left-handed reliever Tyler Holton. Infielder Jonathan Schoop is focusing on increasing his walks to get more playing time, while the Tigers showed off their new LED lights in Friday's win over the San Francisco Giants.
