The most interesting decision appears to be between Blazek and Thornburg, possibly as a long reliever. Both have been stretched out as starters in Spring Training, but the Brewers' rotation is set.
"Blazek I don't think is a problem going from starter to bullpen, if we decided to keep him, he would probably make it as a long man," Roenicke said.
The decision with Thornburg is more complex because he's coming back from an elbow injury and the Brewers would like to find a set role for the right-hander, Roenicke said.
"If he can fit into that role, we're happy with him in our bullpen, if that's what it is," the manager said.
Roenicke did not rule out keeping both Blazek and Thornburg in the bullpen, though.
"So we've really got some tough decisions," he said. "I say it every year, but it's usually between two guys. We've been going back and forth and everybody's got a different opinion, and not just the bullpen, but also the last two spots on the bench."
"Every one of them makes sense a certain way," Roenicke said. "Every one of them brings a certain quality that we would need on this team. And now we have to figure out which one is going to be used more often."
