To create a spot for Vierling, shortstop Trey Sweeney was optioned to Triple-A Toledo. Vierling was out for three months earlier this year with a strained rotator cuff. Only four days after being activated, Vierling went back on the injured list on May 27 with a right shoulder strain.

Vierling's return meant someone had to be sent down, and it was shortstop Trey Sweeney who was optioned to Triple-A to make roster space. Javier Báez will have Saturday off as Zach McKinstry will start at shortstop, again showing just how deep and versatile this Tigers roster has become to make a decision such as Sweeney's so difficult.
