It doesn’t sound like Detroit has an appetite for a six-man rotation to start the season, which means one of Manning, Mize, or Reese Olson could start the year either in the bullpen or in the minors. With Gipson-Long waiting in the wings and a host of other spot starters like Wentz and Alex Faedo on the 40-man roster, the Tigers have the luxury of bringing some of their top pitching prospects along slowly. Wilmer Flores and Ty Madden both reached Double-A last year and look like they’re on the fast track to the majors, and the Tigers’ top pitching prospect, Jackson Jobe, isn’t that far behind. With the depth the team has established, Detroit can really give that trio of young pitchers all the development time they need when they’d otherwise be lined up to make their debuts this year.
