Justin Meram’s second goal of the game lifted Atlanta United FC to a 2-1 win over the Impact Saturday at Mercedes-Benz Stadium.The Impact was in a position to steal a point when Meram scored in the 83rd minute to snap a 1-1 tie. The winning goal came off a corner kick from Leandro Gonzales Pirez. He delivered a ball to the far post where Brek Shea slipped inside on fullback Rudy Camacho and used a touch to find Meram in front.Atlanta, the defending MLS champion, dominated the game and took the lead on a highlight goal from Meram in the 35th minute. He curved a shot into the top right corner just beyond the reach of Impact goalkeeper Evan Bush from 25 yards out.The goals were the first for the veteran Meram since he was acquired from the Columbus Crew last month.Atlanta United dominated the play, outshooting the Impact 15-8 with a 4-1 edge in shots on target. But Montreal managed to tie the game in the 50th minute when Harry Novillp intercepted a pass and fired a shot which caromed into the net off Zakariah Diallo’s thigh. It was the first goal Atlanta has given up at home since April 20.There was a controversial play in added time in the first half. Miles Robinson pulled Camacho down when he was in position to score from the side of the net. A foul call would have resulted in a penalty shot but there was no call on the play.The loss had some implications on the MLS Eastern Conference standings. The win moved Atlanta into fourth place in with 29 points. Atlanta is one point behind Montreal but the champs have three games in hand.Montreal dropped one spot into third place behind D.C. United which drew with Toronto FC 1-1. There was one bit of good news as NYCFC rallied to beat the Philadelphia Union, which leads the table with 32 points.The Impact continued to play without leading scorer Ignacio Piatti and five players who are on international duty. There was semi-good news on that front Saturday as Haiti came from behind to beat Canada 3-2 in the Gold Cup quarterfinals Saturday. That means midfielder Samuel Piette and fullback Zachary Brault-Guillard should be available next Saturday when the Impact plays Minnesota at Saputo Stadium.
