Roark's last start was Sept. 23 against the Mets. Roark worked out in the bullpen after that, but he was not needed in the final six games.
"Obviously, we don't know the rotation -- yet. We'll just wait and see," Roark said. "If I'm starting, that's great. If I'm in the bullpen, I'm fine with that, too. Anything to help out the team. Every time I get on the mound, I'll attack the zone, pitch inside."
Roark had a productive season for the Nationals, going 15-10 with a 2.85 ERA. As a reliever, he is 4-0 with a 1.19 ERA in nine career games.
