"He's yelling and screaming," Cardinals' manager Mike Matheny said with a smile. "He's making sure people are doing things the right way. That's what he does best. I think he knows we like having him around, and he can work with Chris Conroy and the medical staff and work on what he needs.
"We take him wherever it makes sense with his rehab."
With that in mind, Carpenter, who has been out the entire season following surgery on his injured throwing shoulder, said there was no added incentive to making the trip to Philadelphia, where he was on the mound in the National League Division Series against the Phillies last year.
"At times, not just coming here, you think about that," Carpenter said. "It still is and was an exciting time. [The memories are] in my head, so I don't have to come to Philly to remember them. I always enjoy coming here anyway. It's a great ballpark, with great fans and it's fun to compete against them."
