By purchasing the contract of right-hander Virgil Vasquez from Triple-A Toledo, the Tigers protected all of the prospects they wanted from being selected in the Rule 5 Draft. They still had one spot open on the roster, which they chose to keep unfilled for now.
The Tigers may be keeping the spot open in order to use a rule 5 pick to fill it, but that's up in the air right now. They kept spots open last year and filled them with Kenny Rogers and Todd Jones, so the there are still different possibilities.
