Roark could be used as a tandem starter in that game along with Blue Jays right-hander Marcus Stroman, according to MLB.com's Jon Paul Morosi. Roark is scheduled to join Team USA on Sunday, and should make one more start with the Nats before he leaves with teammate Daniel Murphy, who is also playing for Team USA.
"You get to represent your country," Roark said. "And that's one hell of a thing to represent where you're from. Everybody else is doing the same around the world, so it's a cool thing to go head-to-head against other countries and try to come out on top."
Even though Roark threw a career high 210 innings in 2016, he was not hesitant to accept his Classic invitation. In fact, Roark said he wanted to start throwing earlier this offseason than usual so it played into his hands. He began throwing in late November, about a month ahead of his normal starting point.
"I didn't want everything to start going back in place and everything start to feel tight again because I'm not doing the same motion of throwing," Roark said.
Roark will face a lineup featuring Robinson Cano, Jose Bautista, Nelson Cruz and Manny Machado for the Dominican Republic, so he was happy to face a Cardinals lineup featuring several regulars Monday.
"I felt it when we had the intrasquad," he said. "I like to be out there and it's a different kind of animal and you just go out there and you have to compete. Always. No matter if it's against your own guys."
