Jeff Larentowicz scored his first career goal in the 34th minute as the New England Revolution snapped a six-match winless streak with a 1-0 win over the Columbus Crew on Sunday night.
Revolution goalkeeper Matt Reis recorded his seventh shutout of the season and stopped a penalty shot by Eddie Gaven in the 87th minute.
New England (7-7-10), which had lost two and tied four of its last six, took the lead when Larentowicz converted a loose ball after Jose Cancela's corner kick from the left wing.
Columbus (5-12-8) had several good chances, including a breakaway bid by Rusty Pierce in the 29th minute and a hard drive by Duncan Oughton in the 56th that Reis punched away.
Wizards 1, FC Dallas 0
Scott Sealy scored in the 62nd minute for the Wizards.
Driving rain and thunderstorms a couple of hours before the game made for a slick playing surface that affected the players' timing.
Kansas City (8-12-5) got the lone goal thanks to a through ball that wasn't touched. Sasha Victorine sent a sharp pass into the penalty area of FC Dallas (12-8-3), and toward Kansas City forward Eddie Johnson.
But instead of taking the pass, Johnson faked a touch and ran over the ball, allowing it to fall to Sealy, who turned and fired in a left-footed shot from 7 yards out that beat goalkeeper Dario Sala.
