CHICAGO -- Tim Hudson's long rehab process progressed yet again at Wrigley Field on Monday afternoon, when he tested his surgically repaired right elbow with his first live batting-practice session of the year.

Hudson, who is a little more than 11 months removed from Tommy John elbow reconstruction surgery, threw just 18 pitches during this five-minute session that mirrored the one that all Braves pitchers experience during the first or second day of Spring Training.

"I'm still not where I need to be," Hudson said. "My arm strength feels pretty good. There are some things that I need to clean up when I get out there. Still, I'm pretty happy with where I'm at."

Hudson will throw another live batting-practice session on Tuesday and then continue to prepare for his first Minor League rehab start, which is scheduled for July 19 with Class A-Advanced Myrtle Beach.

"It's going to take some time for me to go out there and get used to pitching in a game with live hitters and the added adrenaline rush," Hudson said.

With his current rehab schedule, Hudson likely wouldn't rejoin the Atlanta rotation before Aug. 25. There's also a chance that the Braves could choose to hold him back one more week and activate him after the rosters expand in September.
