San Diego got interest in Guzman in late July, but he wound up staying put for the rest of the season. The 29-year-old took a step back from his previous two seasons with the Padres in 2013, hitting just .226/.297/.378 in 318 plate appearances. Prior to that, Guzman had a .277/.342/.446 slash line through 592 PAs in 2011 and 2012.
Jackson, 25, saw time in 20 big league games for the Cardinals from 2012-13 before being waived in the fall and picked up by Houston.
