The Houston Dynamo are unbeaten in their last four home matches. That bodes well against a Real Salt Lake club that has failed to score in its last three on the road, and has never won at Robertson Stadium.

The surging Dynamo complete a busy week when they take on Real Salt Lake on Saturday night.

Houston (7-7-11) has scored eight times during a 2-0-2 stretch at home, while Real Salt Lake (10-6-6) has gone more than 300 minutes since its last road goal.

The Dynamo are 6-0-1 against Real Salt Lake at Robertson Stadium, winning 2-1 there on a pair of penalty-kick goals by Brad Davis on April 1, 2010. The teams played to a scoreless draw in Utah on May 14 in their first matchup of 2011.

Houston could be fatigued in its third match in seven days. The Dynamo won 2-1 at home over Portland on Sunday and tied 1-all with New England on Wednesday.

"It was a quick turnaround for a game Wednesday night and now we have another quick turnaround Saturday," midfielder Geoff Cameron said.

The Dynamo extended their unbeaten run to four on Bobby Boswell's 90th-minute equalizer against the Revolution.

"The biggest thing is mentally staying strong and staying with it," Davis said. "It took us to the end of the game to get our goal, had a lot of chances, but fortunately we were able to get one."

Midfielder Adam Moffat won't be available Saturday after he was sent off with a second yellow card after the final whistle Wednesday.

Real Salt Lake will also be missing key personnel, as starters Chris Wingert and Will Johnson are out.

Wingert, a defender, broke his left wrist in a 1-0 loss to Toronto FC last Saturday and is expected to miss at least four weeks. Johnson, a midfielder, is suspended due to yellow card accumulation.

RSL has lost three of four overall and is 2-4-3 on the road.

"I think that we're a strong enough team that we shouldn't have the road record that we have right now," coach Jason Kreis told Real Salt Lake's official website. "It should be better."

Salt Lake is in fifth place in the Western Conference with 36 points, although it has played the fewest games in the league.

"Now we're kind of treading water a little bit," midfielder Kyle Beckerman said. "We need to start picking up some points and make sure we're in the playoffs not having to look at the end of the season to get in."

Houston is in fourth place in the tightly packed East. A victory Saturday could move the Dynamo into second.

"I think we're playing good," coach Dominic Kinnear said. "I think the last three, four games we've played, two on the road, I think we've been very good. We've created a lot of chances, we've scored some goals and I just like the way that we're completing the game."
