The Detroit Tigers had a choice at backup catcher: Grayson Greiner or Dustin Garneau.
The answer came Thursday, when the Tigers optioned Greiner to Triple-A Toledo to make room for Eric Haase, set to return before Friday's series opener with the Toronto Blue Jays after a 10-day stay on the injured list with right abdominal strain. (Also: Drew Hutchison, recently designated for assignment, cleared waivers and was sent to Toledo.)
The Tigers acquired Garneau from the Colorado Rockies on Aug. 18. They needed a second catcher upon learning Haase's injury — while nothing severe — would require time away from the big leagues.
