Brayan Pena's minor-league rehabilitation assignment is over. Pena met the Cardinals in Kansas City and figures to come off the 15-day disabled list Tuesday in Kansas City. Pena has yet to make his Cardinals' debut since signing a two-year, $5 million contract to be Yadier Molina's backup. He underwent left knee surgery shortly after Opening Day. The team is hopeful that Pena's arrival will allow them to give Molina more rest. With minor-league journeyman Eric Fryer as the backup, Molina has started 67 of the team's 75 games at catcher. "Sometimes, we take our health for granted," Pena said. "I'm just excited to get back in there. You feel envy when you see these guys playing when you're not healthy."
