AP, Portland :Ignacio Piatti scored late in the first half to lift the Montreal Impact into a 1-1 tie with the Portland Timbers on Wednesday night.Portland (6-6-8) opened the scoring in the 14th minute. Jack McInerney headed in a corner kick by Jack Jewsbury. Montreal goalkeeper Evan Bush missed his attempt at punching the ball clear, and McInerney scored his fifth goal of the season.”I think I got picked. I was supposed to make a near-post run, couldn’t get there,” McInerney said. “Just kind of peeled off, got up and got a head on it.”The Timbers appeared to make it 2-0 in the 34th minute, when Fanendo Adi headed in a cross from Ben Zemanski, but the goal was disallowed, as Adi was called for a foul just before the header.Piatti’s 11th goal of the season lifted Montreal (6-4-8) into the tie.”I think Ignacio is one of the best players in the league. He’s someone that gets chances every game,” Montreal head coach Mauro Biello said. “When you have players like that, they can make things happen out of nothing.”The tie extends unbeaten streaks for both teams. Portland is undefeated in their last eight games (3-0-5), while Montreal’s streak has reached six games (2-0-4).Both teams face quick turnarounds with home games on Sunday. Montreal hosts New York City FC, while Portland welcomes rival Seattle.
