Just as the MLS anthem played both teams started their walk out. In Portland that means that the Timbers Army leads P-T, F-C. They have a drum with a double beat that sounds the constant rhythm. In Seattle, that same time is when the iconic boom-boom-clap starts with its slow-to-fast arrhythmic beats.
The TA’s drum led to early clapping in CenturyLink Field. Fans not in ECS were a bit confused, but then ECS drummed as loud as they’ve ever drummed — BOOM-BOOM and a stadium-wide clap followed.
“The fans that were in the building made it special, as well,” Coach Brian Schmetzer said postgame.
