San Jose Earthquakes extended Houston Dynamo's winless run to four matches with a 1-0 triumph in Texas on Tuesday.
A cleverly taken free-kick by Matias Perez Garcia just after half-time set up Adam Jahn to score as the Earthquakes won for the first time on their four-game road trip, which culminates against the Colorado Rapids on Friday.
The loss was Dynamo's second in a row, following on from two straight draws, meaning they have not tasted victory since a 3-0 triumph over Montreal Impact on April 11.
In the 54th minute, Perez Garcia whipped in a cross just after a team-mate had placed the ball for a free-kick - and with Dynamo's defenders half asleep, Jahn headed home unmarked.
But Bingham palmed Giles Barnes' 58th-minute spot-kick past the post to ensure the Earthquakes maintained their lead.
