The Padres have recalled right-handed pitcher Cory Mazzoni and optioned lefty Chris Rearick to Triple-A El Paso.
Mazzoni will be making his first trip to the major-league regular-season roster. He was acquired from the Mets in a trade before the beginning of the season. Mazzoni has made six appearances with El Paso, giving up one earned run in 8 1/3 innings while striking out 13 and walking one.
