Brek Shea moved equal top of Major League Soccer's goalscoring list with the decisive score in Dallas' 1-0 away win over Toronto on Wednesday.
The 21-year-old Shea, who has worked his way into the senior U.S. squad, joined big-name stars Thierry Henry and Landon Donovan on nine goals, and almost made it 10 in the 61st minute but his shot was blocked by the leg of Toronto goalkeeper Stefan Frei.
Toronto's Joao Plata got the ball in the net in the 53rd-minute, but it was ruled out for offside.
Maicon Santos and Ryan Johnson came close to equalizing in the closing stages, but Toronto ended a third straight game goalless.
In Washington, New England ended a nine-game winless streak and took its first road win of the season with victory at D.C. United.
Chris Tierney's corner was headed in by Stephen McCarthy in the 73rd minute.
The Revolution may have been in the midst of a club-record winless stretch but won their fifth consecutive game against United, which has not won at home since early May.
D.C. missed a penalty late in the first half, with Charlie Davis blasting the ball over the middle of the crossbar.
