Manager Mike Matheny anticipated Peralta will return in a few days to the team's
The Cardinals will consult with the surgeon, Dr. Charlie Goldfarb, to find out when Peralta can return to action.
The Baltimore Orioles have signed infielder Pedro Alvarez to a one-year contract worth $5.75 million. A 29-year-old power hitter, Alvarez has 131 homers in six major league seasons and was an All-Star in 2013. He hit .243 with 27 homers, 77 RBIs and 131 strikeouts last year.
Alvarez, who was not offered a contract by Pittsburgh in December, is likely to get most of his action as the Orioles' designated hitter.
