Sounders fill hole, acquire goalkeeper Frei from Toronto

SEATTLE – The Seattle Sounders quickly filled their goalkeeper vacancy, acquiring Stefan Frei from Toronto FC for a conditional first-round pick in the 2015 SuperDraft.

Tuesday’s trade came a day after the Sounders declined their 2014 contract option on goalkeeper Michael Gspurning.

The 27-year Frei has played in just one Major League Soccer game the past two seasons.

Also Tuesday, D.C. United acquired veteran Davy Arnaud from the Montreal Impact for an international roster spot and Pablo Mastroeni, who played for the United States at the 2002 and 2006 World Cups, announced his retirement.
