Jackson signed a minor league deal with the Phillies on Wednesday, Todd Zolecki of MLB.com reports.
Jackson briefly spent some time with the Angels this season, failing to record a hit in 14 at-bats. He did slash a decent .295/.372/.378 line with the Royals' and Angels' Triple-A affiliates last season, so it's possible Jackson could work his way onto the major league roster with a decent showing during spring training, but he probably won't present much fantasy value until he earns more playing time.
