"We know what we want to do," Roenicke said. "We talked to Mark this morning with Doug [Melvin, the team's GM] and Gord [Ash, assistant GM] and I."
"Mark agrees," Roenicke added. "There's no issues, which is a good thing. There's not shoulder or elbow issues, it's just building up arm strength. For some reason, some guys take longer. I don't know why that is."
Teams are not allowed to place healthy players on the DL, but the Brewers could cite fatigue or weakness for a move with Rogers.
"Whatever doesn't allow your arm to perform at an obvious high level -- there's something there," Roenicke said. "He hasn't got to the place where he needs to be to make an evaluation on him. ... There's something we need to do to build that arm strength, whether it's more long toss, whether it's the trainers' being in there with him to build up the shoulder.
"But the nice thing is he threw great for us last year, and he hasn't had any injuries that would get you to question whether this thing is going to come back. I think he's going to get his velocity back. I feel very confident about that."
