Dempsey led Seattle to a 3-2 road win over FC Dallas, handing the league leaders their first defeat of the season.
With FC Dallas leading 1-0 in the 22nd minute, Dempsey leveled the score by drilling a spectacular 35-yard free kick that bounced off the crossbar and into the net.
In the 75th minute with Dallas leading 2-1, Dempsey sent in a dangerous cross that deflected off FC Dallas defender Stephen Keel for an own goal.
Dempsey continued his top form late into the match, finishing off a nice give-and-go sequence with fellow forward Chad Barrett in the 85th minute to seal the win in his home state.
