PHILADELPHIA -- Ryan Jackson heard his teammates talking, but the infielder wasn't sure exactly what the trade of Tyler Green from the Cardinals to Houston meant for him. Granted, Jackson was sitting in the Dallas/Fort Worth Airport during a layover with Triple-A Memphis and was still shaking off sleep from the flight in from Fresno moments earlier.

"I had just gotten off the plane and heard guys talking," Jackson said. "They told me about the trade and I was like, 'OK, man -- whatever.' Then my manager came over and told me I was coming up."

Jackson -- ranked as the Cards' No. 17 prospect by MLB.com -- returned to Memphis for the night, one in which he admits he tried to shut his eyes but never really slept, and then went to Philadelphia, where he will fill a utility infield role off the bench for St. Louis.

The University of Miami product, who played primarily shortstop but did have chances at second and third for Memphis this season, gives the Cardinals some added depth and replaces what amounts to a disappointing stint for Green with the Cardinals. Jackson hit .269 with a .331 on-base percentage and .398 slugging percentage. Add in 10 home runs, 23 doubles and 45 RBIs, and Jackson gives the Cardinals an option against lefties late in games.

"The first day is always a big deal," Cardinals manager Mike Matheny said. "It's not a courtesy trip. He's going to be put to use and hopefully help us move forward. He impressed us through the spring and he's been consistent, especially lately."

"My dad was on his way to work and I told him he had to reroute and head to Philly," said Jackson, who will have his father, mother and grandfather at Citizens Bank Park for his first game in a Cardinals uniform. "I wasn't thinking about anything but playing as hard as I could. I just came every day and worked hard and tried not to think about [getting the callup.] I just report for duty."

Traveling with Cards, Carp back in Philly

PHILADELPHIA -- Chris Carpenter isn't about to rejoin the Cardinals' rotation, but he is traveling with the team. That type of leadership and experience can't be measured.

"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."

Cards weighing extra rest for Wainwright

PHILADELPHIA -- After a strong outing Sunday in which Adam Wainwright threw a season-high 119 pitches in a 3-1 win over San Francisco, the question is will the Cardinals keep him on his fifth day, or with a day off on Monday give him an extra day of rest and push his start to Wednesday against Arizona.

"We've talked about it, but we haven't come to a solid decision yet," manager Mike Matheny said. "You watch how everything else goes between now and then. The cons are how much of a workload can he put in. Also skipping somebody can be taken the wrong way on a staff that has collectively pitched well this year.

"We look at what we see. If what we see is consistency, which is what we see with Adam, who is pitching better than any time this season. He's not making many mistakes over the heart of the plate. The difference now is the location of his fastball and the effectiveness of his cutter."

Worth noting

• Rehabbing starter Jaime Garcia threw 75 pitches in six innings on Thursday for Double-A Springfield. "The line wasn't as impressive as the way he looked," manager Mike Matheny said. "Six innings on 75 pitches means you're doing something right."

• With Rafael Furcal battling a bad back, Jon Jay filled the leadoff spot of the lineup for the fifth time this season. "You want [your leadoff hitter] to work the count a little better and the bottom line is getting on base," said Matheny. "It's a guy that can't be afraid to be patient." Furcal was in the lineup, but batting eighth.
