Kai Kamara and Graham Zusi scored on penalty kicks in the second half Wednesday night, lifting Sporting Kansas City to a 3-1 victory over the Montreal Impact.

Fans booed through much of the second half after referee Sorin Stoica called Montreal's Patrice Bernier for an accidental hand ball in the area for one penalty and then awarded another after what looked like incidental contact by captain Davy Arnaud.

After Kamara and Zusi converted from the spot to erase a 1-0 deficit, substitute Jacob Peterson put the match away for Kansas City (10-5-2) with a goal from the right side in the 82nd minute as Sporting ended a two-game skid.

Bernier scored in the 49th minute for Montreal (5-11-3), which lost its third straight.
