Tigers promote shortstop Willi Castro from Triple-A Toledo

In a bit of a surprise, the Detroit Tigers have promoted switch hitting shortstop Willi Castro to the major leagues. The move was precipitated by Niko Goodrum being moved to the injured list. Castro is the Tigers 11th ranked prospect according to MLB Pipeline.

The 22-year-old Castro has put together a solid campaign in his first full season at the Triple-A level. He posted a 113 wRC+, with 11 home runs and 17 bases for the Mud Hens this season. Questions have remained about his tendency to be error prone, despite his solid skillset for the position. He’s been charged with 22 errors this season out of 384 chances, but continues to be graded as average or better by the major scouting services.

With less than two weeks to go in the Mud Hens season, the move is a bit of surprise. It remains to be seen whether Castro will get the majority of the reps at shortstop, or whether the Tigers will use him at second base as well.

In another move, catcher Grayson Greiner has completed his rehab from back issues, and was activated from the injured list and assigned to Toledo.
