"After doing everything I did today, and for me to finish on the treadmill without feeling any pain or soreness, it was very good," Pena said. "They say that I'm a little bit ahead of schedule. I wasn't expecting to hit this soon, and for me to go out there and hit the way I did, I felt like a 20-year-old again."
Pena will attempt to repeat the rotation of exercises on Saturday to make sure he's recovering as expected, and then he'll slowly add in more work as he reaches subsequent benchmarks. Pena expects to have a better grasp on a timetable for his return once he resumes catching and squatting.
"I feel like the fans don't know who I am. My teammates don't know who I am," said Pena, who signed a two-year deal with St. Louis over the offseason. "I want to be able to be with my teammates on the baseball field and grind it out with them."
• Outfielder Tommy Pham (left oblique strain) went 1-for-5 with two RBIs and a stolen base in his first two games of a rehab assignment with Triple-A Memphis. The Cardinals have not specified how many at-bats they'd like Pham to take before coming off the disabled list.
• First baseman Matt Adams said he was still dealing with some soreness on Friday, a day after taking a knee to his left leg during a contact play at first base. He underwent treatment prior to Friday's game and completed some light exercises. The Cardinals expected him to be available off the bench.
• The Cardinals placed a limited number of loge and pavilion tickets on sale for the team's Strikeout Cancer Night at Busch Stadium on May 18. For each $15 ticket purchased, the Cardinals will donate $5 to the foundation of former Cardinals reliever Jason Motte, who will be in town that night as a member of the Rockies organization.
