When asked whether Collmenter's success could lead to a more prominent role, manager Kirk Gibson said it might but that the team does not have another clear long-relief option.
"If you pitch him too much [as a setup man], then who's the long guy?" Gibson said.
Gibson presented the possibility that Collmenter could throw multiple innings as a setup man before handing the ball over to closer Heath Bell.
"We'll see where we're at in the game," Gibson said. "It's possible. He could pitch [innings] six, seven and eight.
"We'll come back and see how everybody's throwing and go from there."
