Ok, stick with me here. It'll take some time to explain this one. It's all about an Orton heel turn.
So apparently, The Miz is gradually turning face. Whether you agree with it or not (I personally don't since he's tailor-made as a heel), it seems rather imminent at the moment. So that would explain the pairing here with Randy Orton.
As far as throwing Ricardo Rodriguez in this match, that order can come from SmackDown general manager Booker T. Seeing as though Ricardo and Alberto Del Rio have been sticking their noises in the wrong places, this be a punishment of sorts for both.
If Ricardo wants to get involved in Del Rio's matches, then he'll be really involved here.
But here's the other twist...Orton goes heel.
Miz and Orton would appear to be the heavy favorites given the partner of Del Rio. A 180 from Randy, however, could be in store.
Orton's character has been very strange and rather confusing. So it's really time for a change.
The Viper would RKO Miz at some point during the match, leaving him open for a pin from Del Rio or preferably Rodriguez. This would finally put an end to this feud and put Orton where he belongs as a character.
Until then, Miz would have to be much more over as a face for Orton's turn to be more effective.
