The Cardinals are not considered moving pitcher Carlos Martinez from the bullpen to the rotation, despite losing Joe Kelly to a hamstring injury that landed him on the disabled list Thursday, according to MLB.com.
"You'd be looking at stretching him out just to slow him back down again," Matheny said. "This is one of those scenarios where we just don't know how long it's going to be [for Kelly]. It's not set in stone, and I think you take that risk of pulling [Martinez] out, getting him going just to slow him back down if things [with Kelly] progress quickly."
According to the report, the team prefers to pick a starter from the Triple-A squad in Memphis, rather than move Carlos Martinez into a starting role for a few spot starts. Tyler Lyons and Tim Cooney are both mentioned as possible options for the spot.
Martinez has a 1.86 ERA in 9 2/3 innings of the bullpen, and has yet to throw more than 31 pitches in any outing.
