The Padres called up Song from Triple-A El Paso on Tuesday, AJ Cassavell of MLB.com reports.
Song's promotion comes as a corresponding move to the Padres placing Jake Cronenworth on the seven-day concussion injured list Tuesday. Since being optioned to Triple-A El Paso on April 27, Song has slashed .292/.346/.458 with a home run, three RBI and a stolen base across 26 plate appearances in five games.
