White Sox acquired RHP Simon Castro and LHP Pedro Hernandez from the Padres for OF Carlos Quentin.

Castro (6-5, 210), is the higher regarded prospect of the two, but posted a 5.63 ERA and 1.44 WHIP over 22 appearances between Double-A San Antonio and Triple-A Tucson. Neither player is listed among the Padres’ top 10 prospects. However, considering the White Sox's farm system is barren of talent, they should rank much higher within their organization.
