Joseph was called up by the Philles on Friday.
Due to Darin Ruf's putrid performance at the plate so far this season, the Phillies were willing to give Joseph a promotion from Triple-A Lehigh Valley. The 24-year-old has been annihilating Triple-A pitching, batting .347 with six home runs and 17 RBI thus far, so he'll try to translate that to the big leagues. He'll likely slot into the short end of a platoon at first base with Ryan Howard.
