"It went fine. I think we're on track as we've planned," Bailey said. "Obviously, the weather made it more difficult but overall, I think stuff went as we expected.
"There's always going to be those aches, I guess, but not pain. If you throw enough, you understand what that means. We'll continue the treatment and what we're doing."
Bailey, who had his operation in September, remains iffy to be ready by Opening Day. But he has not given up on being able to take his first turn in the rotation.
"It's still so far away," he said. "We have over a month. I haven't ruled out anything but I haven't completely kept the door open. We just have to continue with the process. After the first three or four bullpens, we'll have a better idea of where it's at. Right now, it's still so new. It would be like that if you're healthy."
Meanwhile, Reds lefty reliever Sean Marshall -- recovering from June shoulder surgery -- has resumed throwing from flat ground for a week since he was shut down following a setback. There is no date, yet, for when Marshall will advance to throwing from a mound.
"It's a hard one to answer," Reds manager Bryan Price said. "What we're trying to do is get him to where he is completely pain free. He's been a little bit achy but nothing that would prevent him from throwing. It's a part of the process."
