The Padres optioned infielder Jace Peterson to Triple-A El Paso and designated pitcher Bobby LaFrombroise for assignment Wednesday.
The moves were made to clear a 25-man and a 40-man roster spot for Cameron Maybin, who returned from a 25-game suspension Wednesday. Peterson is just 6 for 53 in 27 games with the Padres. LaFromboise owns a 4.75 ERA and 45:21 K:BB ratio in 53 innings with El Paso.
