Coming in the second half of a game that was USA all the way, Wondolowski cleaned up a deflected pass from Landon Donovan and calmly slotted the ball into the net to extend the Nat's lead to 3-0 over Guatemala.
Meanwhile, another Earthquake found the back of the net against Guatemala. After narrowly missing a chance to give the USMNT their first goal with a thunderous header in the first half, Clarence Goodson finally got on the score sheet with a "Never Say Die" effort in a goal mouth scramble. The soon-to-be Earthquakes starting center back pushed the U.S. advantage to 5-0 with his goal.
