In their continued quest to build a championship soccer squad, the Philadelphia Union acquired Chicago Fire defender Austin Berry in exchange for allocation money.

The terms of the deal were not immediately released, but the Union do accumulate one of Chicago’s defensive anchors in the deal.

“Austin is a talented central defender that will add quality to our back line,” team manager John Hackworth said. “He already has a lot of MLS experience and we think he is the right fit to help strengthen our central defense. We’re happy to have a player of his caliber and look forward to him joining the team.”

The 2012 MLS rookie of the year will join the Union this week for preseason training in Deltona, Fla.
