• Center fielder Billy Hamilton (sore right shoulder) was allowed to resume hitting by the medical staff Wednesday morning.
"Just a little bit, but I won't be doing full stuff until [Thursday]," said Hamilton, who hasn't played since colliding with a wall against the Cubs on Friday. "It feels good. I don't know about when I'll play a game -- hopefully soon."
• Starting pitcher Homer Bailey, rehabilitating from surgery that repaired a torn flexor mass tendon near his right elbow, threw his fifth bullpen session of camp Wednesday morning.
"Thumbs up," said Bailey, who is scheduled to face hitters for the first time in live batting practice Saturday. He is expected to have two live BP sessions before he's allowed to work in a game.
• Like Hamilton, catcher Devin Mesoraco (concussion) was slated to be reexamined by Dr. Tim Kremchek on Wednesday. Mesoraco has been making progress since he was injured Saturday by a foul tip hitting his mask.
"Devin will increase our baseball activity as well," Reds manager Bryan Price said Wednesday morning. "He's already in the cage hitting. He'll go out there and throw."
• Reliever Sean Marshall, who is trying to come back from left shoulder surgery, appears to not be close to getting on a mound. Marshall has flexibility issues.
"He can throw the ball OK," Price said. "He still has a little bit of biceps tendinitis, which isn't of great concern. His evaluation went very well. The feeling is he needs more range of motion. That's consistent with someone who did a lot of work on the shoulder in the offseason. It's strong, but you've got to create the flexibility portion. That's given him some tedious achiness that we'd like to get out of there."
