#7 Ronda Rousey vs. Ruby Riott

Yes, this match really looks like it will be tonight's main event. Despite there being essentially no buildup for Riott, this match will main event because of the larger angle involved. When Charlotte Flair revealed she would be sitting at ringside, that all but guaranteed that it would go on last.
The Ronda/Charlotte/Becky angle has been overexposed to death already. I don't expect that to stop here. Unfortunately, we're going to have to go through another two months of this convoluted nonsense.
Look who just shut down all of Tony Khan's critics! More HERE.
Becky Lynch might appear tonight, too, which further adds credence to its being the main event on the evening.
Ultimately, Riott is just there to fill space. This is more an angle than a match, an angle in which Ronda Rousey herself already feels like a third wheel in. No matter how much of a disservice it does to everyone involved, this is going to be the main event.
