And I agree that would be a bit odd now that Jordan Hicks is out, and Martinez is performing as the closer, as he usually does.
As always, it would depend on the return.
And the organization's cooling on Martinez is relevant. That the trade discussion surrounding Martinez is still going on and has been hovering around for this long says a lot about his long, strange trip to this place.
He wants to be a starter, but has not been physically capable of doing that. The team has been frustrated publicly with him at times regarding his physical health and dedication to the routine that maximizes it. Carlos Martinez was once a face of this team. Now, he's almost an afterthought until he comes out of the bullpen.
I've said this before, but I would not be surprised if Martinez's career as a Cardinal ends in a trade. Right now, though, would seem a bit odd. They need him closing games.
