When you only have five matches to choose from over a weekend, it's not easy to come up with a whole bunch of teams to put on upset alert.

Sometimes, you have to really stretch the meaning of the word "upset."

Which is what I've done for this weekend's matches in MLS.

Upset Alert #1: D.C. United v. Toronto

It's really a stretch to call either team winning this match an upset. Considering they have two wins between them in the league this season, the word for either team winning this match would probably be "shocking," "unbelievable" or "miraculous."

However, I will put D.C. on upset alert due to the fact that they will be feeling pretty good about themselves after their 3-1 win over the Philadelphia Union in the fourth round of the U.S. Open Cup on Wednesday night. Dwayne De Rosario's hat trick in that game was 1 more goal than DC scored in the entire month of May, unless you count the penalty kicks in their game against the Richmond Kickers in the third round of the Open Cup.

Toronto, on the other hand, has not played since June 1—a 1-1 home draw with Philadelphia. They've also scored twice as many goals in league play as D.C. United. That's not saying much, considering D.C. only has six goals.

Upset Alert #2: Portland v. Dallas

Front-running Dallas should be on upset alert when they visit the Rose City on Saturday.

While both clubs posted clean sheets in the fourth round of Open Cup play, Dallas shouldn't let the fact they knocked off Houston go to their heads. Houston's substitute-heavy lineup didn't really stand much of a chance. First-choice goalkeeper Tally Hall was among the spectators at FC Dallas Stadium for Houston's 3-0 defeat.

Thoughts? Think I'm loony? Let me know in the comments.
