Cards activate IF Peralta after missed month
Peralta has not played in the majors since April 15. He had been seeing reduced playing time after starting the season with a .120 batting average before he landed on the DL on April 20 with an upper respiratory infection.
He showed some progress at the plate in a rehab assignment with Triple-A Memphis, going 4-for-11 with a double and two RBIs in three games.
In a corresponding move, rookie outfielder Magneuris Sierra was optioned to Double-A Springfield. Sierra had hit .376 in seven games with the Cardinals.
