Real Salt Lake remain second in the Eastern Conference after their third consecutive goalless draw.
Salt Lake welcomed Vancouver Whitecaps to the Rio Tinto Stadium and were on the back foot for much of the first half.
Dane Richards and Alain Rochat both missed chances for Vancouver before the home side found their rhythm and missed two good chances of their own just before the break.
Darren Mattocks thought that he had given Vancouver the lead on 57 minutes but saw his strike disallowed for offside.
The home team responded well, creating chances through Luis Gil and Alvaro Saborio but neither side could find the breakthrough and it ended 0-0.
Result: Third straight goalless draw for Salt Lake
