After two outings in extended spring camp, the Tigers sent Marte out on a rehab assignment to high Class A Lakeland. He was scheduled to pitch for the Flying Tigers on Thursday night against Port St. Lucie, the Mets' Florida State League affiliate.
The Tigers can keep Marte on rehab for up to 30 days, whether in A ball or at a higher level. There's no strong indication whether the Tigers would do that or not, given the state of their bullpen compared with the amount of time Marte lost. If they go the full 30 days, though, they'd have to decide from there whether to activate Marte or option him to the Minors.
A day before the injury, the Tigers had announced that Marte was slated to make the Opening Day roster. His injury created a spot for left-hander Duane Below, who has been on the big league club all season.
Detroit has had a relative revolving door elsewhere in the bullpen, from Daniel Schlereth to Thad Weber to two different stints for Brayan Villarreal, who was just recalled from Triple-A Toledo on Thursday.
