SEATTLE (AP) — Thousands of fans are celebrating the Seattle Sounders' MLS Cup victory over Toronto with a jubilant parade through downtown Seattle.

Crowds lined the streets Tuesday chanting "Seattle ... Sounders," waving signs and cheering as a procession of trolley buses carried players and coaches along Fourth Avenue.

Police officers walked alongside the buses, as players leaned out to shake hands with fans and sign autographs. At one point, defender Roman Torres could be seen thrusting the trophy into the air.

The sea of green and blue colors made its way down Fourth Avenue toward Seattle Center, where a rally will celebrate the team's dramatic victory on penalty kicks.
