The Giants have designated outfielder Roger Kieschnick for assignment, reports Andrew Baggarly of CSNBayArea.com (via Twitter).
The 27-year-old didn't distinguish himself in 34 plate appearances this spring, hitting just .172/.294/.172, and hasn't managed to hit well in limited MLB action up to this point. He's been more of a force in the minors, however, with a .273/.339/.497 line in Triple-A last season.
