The Seattle Sounders are tied for first place in the Western Conference and Supporters' Shield standings, and they're also tops when it comes to the AT&T Goal of the Week.

Marco Pappa's gorgeous cutback-and-chip finish vs. the Colorado Rapids has won the Week 30 race by a landslide, garnering more than 80 percent of the vote. His victory marks the ninth time a Sounders player has won GotW this season, and the fifth time in the last seven weeks.

Pappa's goal, set up by a highlight-reel backheel from Clint Dempsey, was the third strike in a 4-1 rout for Seattle at Dick's Sporting Goods Park. Pappa, Dempsey and the rest of the Sounders host the Vancouver Whitecaps on Friday night in a rivalry match which will determine this year's winner of the Cascadia Cup (10 pm ET, NBCSN/NBCSports.com in US, TSN in Canada).
