Bailey, who hasn't pitched in a game since July 20, threw a bullpen session Sunday and reported no setbacks. He played catch Monday and will throw a simulated game or bullpen session on Tuesday.
"We're still a couple days away, but it's getting close," Bailey said. "Each and every day you're feeling better and now that I'm feeling good, it's just about getting back into baseball and game form."
Bailey said he still doesn't know whether he will need a Minor League rehab assignment, saying the team will assess the situation on Tuesday.
"That's up to them," Bailey said. "I haven't talked to them too much about it. ... Hopefully by the weekend I will be good to go."
