Brad Davis of the Dynamo failed to convert a penalty kick in the 76th minute.
Houston (12-7-9) extended its home unbeaten streak to 22 matches and snapped a four-match winless streak overall. The Dynamo are 8-0-1 in home games against Real Salt Lake (14-11-4), which nearly secured its first ever win in Texas, but Houston goalie Tally Hall saved Nat Borcher's header attempt. Real Salt Lake is 0-18-3 against FC Dallas and Houston on the road.
Both teams played without several players because of international callups, suspension or illness. Dynamo head coach Dominic Kinnear was given a red card and was ejected in the 90th minute.
