Vancouver goalkeeper Jay Nolly and Chicago 'keeper Jay Conway combined for six saves in a 0-0 tie between the MLS teams Saturday night.
Chicago extended its winless streak to six matches (0-3-3), while the expansion Whitecaps have gone 0-4-4 since winning their opening match.
"Chicago dominated us a little bit in the first half, but I felt we came out strong and dominated after the break," said Whitecaps FC head coach Teitur Thordarson. "We knew that the Fire were dangerous on the right flank, and they caused us some problems in that area of the pitch before the break.
"We managed to correct these things at halftime and I felt we were able to take over proceedings in the second half. We managed to open them up, but we were unable to score the winner."
With four saves, Nolly had the busier evening, especially in the first 55 minutes. Chicago took four shots in the first half, and Nolly was forced to cover the ball with Marco Pappa breaking in five minutes into the second half.
Conway was pressed into service in the last 15 minutes, his big play beating forward Eric Hassli to a loose ball after Hassli misfired from point-blank range.
The first half was punctuated by three Chicago misfires and one solid chance. Forward Diego Chaves failed to shoot before being ridden off the ball in the penalty area in the 18th minute. He sent a shot off the right goalpost in the 44th.
In between, midfielder Dominic Oduro sailed a close-in shot over the crossbar, and Nolly made a diving save on the drive by Pappa.
