MLB.com’s Jenifer Langosch provides the update:
Chris Carpenter threw his fourth bullpen session on Wednesday and is expected to add the challenge of facing hitters the next time he gets on the mound.
Assuming Carpenter doesn’t feel any day-after pain from his latest work, the right-hander will throw batting practice during the team’s weekend series in Kansas City
Carpenter has been on the disabled list all season with a nerve issue in his neck and shoulder that began bothering him during the second week of spring training.
“I feel good. I really do,” the veteran righty told Langosch on Wednesday. “My shoulder feels good. My body feels good. The effort level has been there, too. … I feel good, and I’m looking forward to the next step.”
Carpenter will need to make three or four minor league rehab starts before rejoining the front end of the Cardinals’ starting rotation. If he’s able to avoid setbacks, he could be ready for MLB action by late July.
The 36-year-old right-hander posted a 3.45 ERA across a major league-high 237 1/3 innings last year before going 4-0 with a 3.25 ERA in six postseason outings (three of which were World Series starts).
The 2012 Cards climbed to one game over .500 (35-34) with Wednesday night’s 3-1 victory over Detroit.
