Update: It didn't take long for the "set roster" to change. Luis Marte has been placed on the disabled list due to a hamstring injury and has been replaced by Duane Below.
The Tigers announced this morning that they have placed Brandon Inge on the 15-day disabled list with a strained groin. The opening day 25-man roster is now set, but two decisions will have to be made in the second week. First, someone will have to be removed when pitcher Drew Smyly is recalled to make his first start on April 12. Then another move will be necessary when Inge comes off the disabled list on April 14. The current roster is shown below.
