Wondolowski's goal -- his league-leading 13th of year -- came at the end of a throw-in from Justin Morrow. His toss was headed on by Alan Gordon and Wondolowski managed to redirect it past Nick Rimando into the net.
Gordon broke a scoreless tie in the 75th on a header for the Earthquakes (10-3-3), who used the three points to vault over Real Salt Lake and into first place in the Western Conference.
Javier Morales briefly tied the score for Salt Lake (10-5-2) in the 79th, scoring on a free kick from 24 yards out.
