Timbers and DC United trade goalies

The Portland Timbers have acquired goaltender Troy Perkins from D.C. United for goaltender Steve Cronin.

The Timbers, who join Major League Soccer as an expansion team next year, will also send D.C. United allocation money as part of the trade announced Friday. United will retain a portion of Perkins' salary budget for next season.

Perkins, the 2006 MLS goalkeeper of the year, returned to United last year after spending two seasons with Valerenga in Norway.

He has played five seasons in MLS, appearing in 77 regular-season matches with a 36-19-22 record, including 19 shutouts. He has a 1.22 goals-against average.

Cronin has appeared in 56 regular-season matches over two seasons for Portland's second-division side with a 26-11-19 record. He has played previously for the San Jose Earthquakes and the Los Angeles Galaxy.
