The Vancouver Whitecaps have stretched their unbeaten run to six games with a comfortable 3-0 win against the Chicago Fire.

An in-form Whitecaps side were put under pressure early on by the Fire, who had efforts on goal in the opening exchanges from Chris Rolfe, Mike Magee and Dilly Duka.

After long periods of frustration, Vancouver broke the deadlock on 66 minutes through Brazilian striker Camilo Sanvezzo, who guided a cross from Brad Knighton into the bottom corner.

Sanvezzo made it a brace soon after, netting his 12th of the season from close range to become Major League Soccer's top scorer.

Kekuta Manneh wrapped up all three points for the home side by scoring six minutes from time, as a last-gasp consolation from Patrick Nyarko was not enough to prevent back-to-back defeats for the Fire.
