Andres Romero, Marco Di Vaio score as Montreal Impact down Chicago MONTREAL, April 27 (UPI) -- Andres Romero netted his first MLS Saturday and the Montreal Impact posted a 2-0 victory over Chicago. The Argentine striker gave the Impact all the scoring they would need in the 57th minute when he took a pass from Andrea Pisanu on the left wing, got past a Chicago defender and put it in the top right corner. Marco Di Vaio doubled the lead in the 76th with his fourth tally of the season for Montreal (5-1-1), which is battling Sporting Kansas City for the top spot in the Eastern Conference. Sean Johnson made four saves for the Fire (2-5-1), who lost Jeff Larentowicz for their next match after he picked up a red card for tripping Pisnau during a breakaway in the 64th minute.
