Who will be the closer on June 1?

Bruce Rondon was added to the Tigers roster yesterday, replacing Octavio Dotel, who was placed on the 15-day disabled list with elbow soreness. You know a little bit about Rondon and what we can expect from him. Then, Jose Valverde was added to the roster, replacing Duane Below, who was recently designated for assignment. Leyland said yesterday that he will use Valverde in a save situation. The veteran gets the first shot at the job. Will he hold it? What if Rondon is lights out? Let us know what you think.
