Why not Bruce Rondon as current Detroit Tigers' closer? These are the reasons
But Rondon still has command problems. June 5, he walked four in two thirds of an inning at Columbus. The issue is accelerated at the major league level because hitters don't swing at nearly as many bad pitches. Also, Toledo isn't exactly the best place to groom a closer right now. The Mud Hens are awful, winning the fewest games in the International League (26) so far this season.
If the Tigers were to call up Rondon, it would be much smarter to break him in a lesser role than closer. Right now, it's highly doubtful his command of the baseball would hold up in such pressure-packed situations.
